The Bitstream Vera family includes serif, sans serif, and monospaced fonts, \begin_inset Foot collapsed true \layout Standard The text of this document is set in Bera Serif and Mono\SpecialChar ~ \begin_inset LatexCommand \cite{bera} \end_inset , a repackaging of Bitstream Vera for TeX. \end_inset and all three fonts have normal, oblique, bold, and bold oblique faces. Bitstream Vera is primarily intended as a screen font (though it also works well as a print font) and has hinting for display on low-resolution devices such as computer monitors and projectors. All three fonts have large \emph on x \emph default height, wide letters and spacing, and \begin_inset Quotes eld \end_inset open \begin_inset Quotes erd \end_inset letters, \begin_inset Foot collapsed true \layout Standard For instance, compare the lowercase \begin_inset Quotes eld \end_inset e \begin_inset Quotes erd \end_inset of Arev Sans with that of Helvetica. \end_inset resulting in fonts that are extremely easy to read at small sizes or on projected displays. \layout Standard Tavmjong Bah created Arev Sans \begin_inset Foot collapsed true \layout Standard Per the license for Bitstream Vera, any derivative fonts must have a different name. \end_inset by extending Bitstream Vera Sans to include Greek, Cyrillic, and many mathemati cal symbols \begin_inset LatexCommand \cite{arev} \end_inset . The new glyphs added by Bah accurately capture the feel of the Latin letters and so seamlessly integrate into the font. Bah's intention was to add symbols that are useful for technical writing, and hence the Greek letters are typical of those used in mathematics and science and not of the letters used in writing the Greek language. \begin_inset Foot collapsed true \layout Standard Specifically, alpha is not the same as lowercase \begin_inset Quotes eld \end_inset a, \begin_inset Quotes erd \end_inset nu is not the same as lowercase \begin_inset Quotes eld \end_inset v, \begin_inset Quotes erd \end_inset and Upsilon is not the same as uppercase \begin_inset Quotes eld \end_inset Y. \begin_inset Quotes erd \end_inset \end_inset At the author's request, Bah also added several alternate glyphs for some of the Latin and Greek letters. This was mainly done so that all of the letters can be clearly distinguished when in mathematics and not surrounded by other letters or even aligned with the baseline. \begin_inset Foot collapsed true \layout Standard The lowercase \begin_inset Quotes eld \end_inset l \begin_inset Quotes erd \end_inset and the uppercase \begin_inset Quotes eld \end_inset I \begin_inset Quotes erd \end_inset in particular are almost identical in Bitstream Vera Sans. The lowercase phi and original uppercase Phi in Arev Sans are also difficult to distinguish without a baseline. \end_inset Additionally, several alternate glyphs were added that are \begin_inset Quotes eld \end_inset warmer \begin_inset Quotes erd \end_inset or more \begin_inset Quotes eld \end_inset humanist \begin_inset Quotes erd \end_inset than the strict \begin_inset Quotes eld \end_inset geometric \begin_inset Quotes erd \end_inset glyphs. \begin_inset Foot collapsed true \layout Standard The extra glyphs include \begin_inset Quotes eld \end_inset a, \begin_inset Quotes erd \end_inset \begin_inset Quotes eld \end_inset i, \begin_inset Quotes erd \end_inset \begin_inset Quotes eld \end_inset l, \begin_inset Quotes erd \end_inset \begin_inset Quotes eld \end_inset u, \begin_inset Quotes erd \end_inset \begin_inset Quotes eld \end_inset v, \begin_inset Quotes erd \end_inset \begin_inset Quotes eld \end_inset w, \begin_inset Quotes erd \end_inset \begin_inset Quotes eld \end_inset x, \begin_inset Quotes erd \end_inset and uppercase Pi and Phi. The florin is used as an alternate \begin_inset Quotes eld \end_inset f. \begin_inset Quotes erd \end_inset \end_inset These extra glyphs add a degree of warmth to mathematics written in Arev Sans that is not achieved with other sans serif fonts. \layout Standard \begin_inset Float figure wide true collapsed true \layout Standard \align center \begin_inset ERT status Collapsed \layout Standard \backslash framebox{ \end_inset \begin_inset Graphics filename fontsample.eps \end_inset \begin_inset ERT status Collapsed \layout Standard } \end_inset \layout Caption \begin_inset LatexCommand \label{cap:fontsample} \end_inset Font sample of Arev Sans text and math. \end_inset Figure\SpecialChar ~ \begin_inset LatexCommand \ref{cap:fontsample} \end_inset shows a sample of Arev Sans being used for text and mathematics. The primary use that the author sees for Arev Sans in LaTeX is for presentation s, and especially for those that are displayed with a computer projector. The attributes of Bitstream Vera and Arev mentioned above make Arev particularl y suited for this purpose. Besides Arev, there are only a few other options for sans serif fonts in LaTeX, and none of them are entirely satisfactory. Computer Modern sans serif and the SliTeX sans serif \begin_inset Foot collapsed true \layout Standard Arev Sans is actually very similar to SliTeX sans serif ( \family typewriter lcmss \family default ) in that both have large \emph on x \emph default height, have wide letters and spacing, and have \begin_inset Quotes eld \end_inset open \begin_inset Quotes erd \end_inset letters. Arev Sans is heavier than SliTeX sans serif though, which makes it more suitable for computer projectors. \end_inset fonts can be used for text, but Computer Modern roman is still used for mathematics. Walter Schmidt's Computer Modern Bright \begin_inset Foot collapsed true \layout Standard Harald Halders created Type 1 Postcript font versions of the \family typewriter cmbright \family default fonts called \family typewriter hfbright \family default . The fonts were created by tracing high resolution bitmaps, and so are not perfect. However, scalable Type 1 fonts greatly improve the quality of Postscript and \family typewriter .pdf \family default files on computer screens and projectors. \end_inset ( \family typewriter cmbright \family default \begin_inset LatexCommand \cite{cmbright} \end_inset ) is a sans serif family that includes both text and mathematics, but is very thin and does not display well on a computer projector. Kerkis Sans \begin_inset LatexCommand \cite{kerkis} \end_inset is based on Avant Garde and includes Greek sans serif glyphs, but is also very thin. Helvetica and other PostScript sans serif fonts can be used for text and for Latin letters in mathematics, but they do not have matching Greek letters or the proper weight for geometric mathematical symbols. \layout Standard The \family typewriter arev \family default package works well with the LaTeX package \family typewriter beamer \family default \begin_inset LatexCommand \cite{beamer} \end_inset with the \family typewriter professionalfonts \family default option. \begin_inset Float figure wide false collapsed true \layout Standard \align center \begin_inset ERT status Collapsed \layout Standard \backslash framebox{ \end_inset \begin_inset Graphics filename prosper-arev.eps scale 90 keepAspectRatio \end_inset \begin_inset ERT status Collapsed \layout Standard } \end_inset \layout Caption \added_space_top -1.75em* \begin_inset LatexCommand \label{cap:ArevSans} \end_inset Arev Sans \end_inset \begin_inset Float figure wide false collapsed true \layout Standard \align center \begin_inset ERT status Collapsed \layout Standard \backslash framebox{ \end_inset \begin_inset Graphics filename prosper-lcmss.eps scale 90 keepAspectRatio \end_inset \begin_inset ERT status Collapsed \layout Standard } \end_inset \layout Caption \added_space_top -1.75em* SliTeX font ( \family typewriter lcmss \family default ) \end_inset \begin_inset Float figure wide false collapsed true \layout Standard \align center \begin_inset ERT status Collapsed \layout Standard \backslash framebox{ \end_inset \begin_inset Graphics filename prosper-cmss.eps scale 90 keepAspectRatio \end_inset \begin_inset ERT status Collapsed \layout Standard } \end_inset \layout Caption \added_space_top -1.75em* Computer Modern sans serif ( \family typewriter cmss \family default ) \end_inset \begin_inset Float figure wide false collapsed true \layout Standard \align center \begin_inset ERT status Collapsed \layout Standard \backslash framebox{ \end_inset \begin_inset Graphics filename prosper-cmbright.eps scale 90 \end_inset \begin_inset ERT status Collapsed \layout Standard } \end_inset \layout Caption \added_space_top -1.75em* CM Bright \end_inset \begin_inset Float figure wide false collapsed true \layout Standard \align center \begin_inset ERT status Collapsed \layout Standard \backslash framebox{ \end_inset \begin_inset Graphics filename prosper-kerkis.eps scale 90 \end_inset \begin_inset ERT status Collapsed \layout Standard } \end_inset \layout Caption \added_space_top -1.75em* Kerkis Sans \end_inset \begin_inset Float figure wide false collapsed true \layout Standard \align center \begin_inset ERT status Collapsed \layout Standard \backslash framebox{ \end_inset \begin_inset Graphics filename prosper-helvetica.eps scale 90 \end_inset \begin_inset ERT status Collapsed \layout Standard } \end_inset \layout Caption \added_space_top -1.75em* \begin_inset LatexCommand \label{cap:Helvetica} \end_inset Helvetica \end_inset Figures\SpecialChar ~ \begin_inset LatexCommand \ref{cap:ArevSans} \end_inset -

SliTeX sans serif is loaded into \family typewriter beamer \family default using TeXPower's \family typewriter tpslifonts.sty \family default \SpecialChar ~ \begin_inset LatexCommand \cite{texpower} \end_inset . \layout Section Implementation \layout Standard With internationalization of computer software and the growing use of Unicode, many free scalable fonts are available that include both Latin and Greek letters. However, making use of these fonts for mathematics in LaTeX is a nontrivial task: not only are there many subtleties to using fonts in LaTeX, but the documentation is scattered among many sources and there are few examples to consult. The author hopes that the \family typewriter arev \family default package can serve as a template for others who wish to create new math font packages for LaTeX. \layout Standard The excellent GPLed font editor FontForge\SpecialChar ~ \begin_inset LatexCommand \cite{fontforge} \end_inset was used by Bah to create Arev Sans and was used by the author for creating PostScript \family typewriter pfb \family default , \family typewriter afm \family default , and TeX \family typewriter tfm \family default files. The Bash shell script \family typewriter afmtoglyphlist \family default was used to extract the glyph names from the \family typewriter afm \family default file into a list that a \family typewriter fontinst \family default script used for renaming glyphs. The magic of \family typewriter fontinst \family default was used to create virtual fonts and font metrics, LaTeX font definition files, and the \family typewriter dvips \family default map file. \layout Standard The vertical placement of math accents requires the accents to be appropriately placed for characters 1 ex high. The accents also need to have a zero depth, which is set by the file \family typewriter fixot1accents.mtx \family default (based on their bounding boxes, the accents naturally have negative depths). Horizontal placement of math accents is done by centering the accent over the character, and then adjusting the position by the kern between the character on the left and a special character called the \emph on skewchar \emph default . To better visualize the placement of the accents, the graphical kerning dialog box in FontForge was used, and then the script \family typewriter afmtokernaccent \family default extracts this kern information from the \family typewriter afm \family default file and creates \family typewriter mtx \family default files that calculate the appropriate kern. The one difficulty in implementing this in \family typewriter fontinst \family default is that the kerning data must be reglyphed before applied to the font metrics. \layout Standard Arev Sans is used for all letter-like symbols, including Latin and Greek letters. Arev Sans includes many mathematical symbols, but not the full range of symbols included in Computer Modern or the AMS symbol fonts. The Math Design Bitstream Charter\SpecialChar ~ \begin_inset LatexCommand \cite{mdch} \end_inset bold math font comes very close to the weight of Arev Sans, and so is used for the majority of geometric symbols \begin_inset Foot collapsed true \layout Standard The Math Design Bitstream Charter math fonts have a few minor flaws: for instance, in the formation of square root symbols and overbraces. However, most of the symbols are of fine quality, and the range of symbols is impressive. \end_inset . Computer Modern is used for the default calligraphic font, Fourier-GUTenberg\SpecialChar ~ \begin_inset LatexCommand \cite{fourier} \end_inset for blackboard bold (since the letters are sans serif), Ralph Smith Formal Script for script, and the AMS font for fraktur. One disadvantage of using so many different fonts for mathematics is that TeX can only have sixteen simultaneously loaded fonts, and the Arev package comes very close to this limit. \layout Standard The file \family typewriter mathtesty.tex \family default is a combination of the file \family typewriter mathtestx.tex \family default from the \family typewriter mathptmx \family default package\SpecialChar ~ \begin_inset LatexCommand \cite{mathptmx} \end_inset and the \family typewriter symbols.tex \family default file of David Carlisle. It is very useful for testing all of the math styles and symbols for a given font setup. \layout Standard There are three LaTeX packages for use with Arev Sans: \family typewriter arev \family default , \family typewriter arevtext \family default , and \family typewriter arevmath \family default . The \family typewriter arev \family default package simply loads both \family typewriter arevtext \family default and \family typewriter arevmath \family default . \family typewriter arevtext \family default changes the default text font (both roman and sans serif) to Arev Sans. \family typewriter arevtext \family default also changes the default typewriter font to Bera Mono, a repackaging of Bitstream Vera Mono for TeX. \family typewriter arevmath \family default sets the math fonts as described above. In addition to the normal styles, the \family typewriter \backslash mathbm \family default command changes the math font to bold italic. \layout Standard Variant letters defined by \family typewriter

The fonts may also be modified and extended, as long as the resulting fonts are released under a different name. Arev Sans is released under the same license as Bitstream Vera. However, Arev's creator Tavmjong Bah requests that TrueType versions of Arev be obtained from his website at \begin_inset LatexCommand \cite{arev} \end_inset instead of being converted from the Postscript fonts included with the LaTeX package.
