However there are writing +scripts supported by the sans-serif but not by serif. + +For an overview of which scripts and sets of symbols are supported by +which face, see the FreeFont 'coverage' web page. + +Font features +============= + +FreeFont has numerous font "features" that perform alterations to the basic +letters of the font, replacing them with other letters, or positioning them +with respect to other letters. + +Many features are activated automatically, but in some environments, they +present some user control. This documents those features with user control. + +Language-specific features +========================== + +Some OpenType font features are activated only when the text is specified to +be of a certain language. + +This is done in HTML by enclosing the text with a tag whose 'lang' attribute +is set to the appropriate ISO 632.2 language code. In a word processor, +any block of text can be given a language setting. + +Latin +----- +Catalan ligature improving l·l +Dutch ligatures for ij, IJ +Sami localized form for letter Eng +Turkish overrides ligatures fi ffi of Latin + +Cyrillic +-------- +Ukrainian ligature for double i-diaresis +Serbian/Macedonian localized letters be, and more in italic +Bulgarian style set for modern glyphs + +Hebrew +------ +Yiddish raised vowels under yo + +Devanagari +---------- +Sanskrit much larger set of ligatures + +Hindi, Marathi better spacing of Western punctuation marks + +Indic languages +--------------- + +The 'danda' character is encoded in Unicode only in the Devanagari range. +When writing in scripts of other Indic languages, this same character is to +be used. But the shapes and line thicknesses of glyphs vary slightly from +one script to another, so the same glyph for 'danda' may not fit all scripts. + +By specifying the language of the text, an appropriate glyph for 'danda' +will be obtained. + +Style sets +========== + +These replacements are activated by specifying a "Style Set". +These features are accessible only from typesetting software. + +Cyrillic Bulgarian modern (ss01) + +Devanagari Bombay (ss02), Calcutta (ss03), Nepali (ss04) + +Discretionary features +====================== +These features are accessible only from typesetting software. +Typically the user must specifically request them. + +Unless otherwise noted, these are available only in FreeSerif. + +Ligatures and substitutions +--------------------------- + +Arabic, Armenian, Hebrew, German, Dutch + +Small captials +-------------- + +A limited set of specially drawn small capital letters in Latin. + +Superscript and subscript +------------------------- + +Transform a limited set of characters--mostly Latin letters and numerals-- +to versions well-sized and positioned as superscript or subscript. + +Numeral styles +-------------- + +The default numerals of FreeSerif are mono-spaced and of even height. +It also features proportionally-spaced numerals, and "old-style" numerals-- +those which vary in height and sometimes go beneath the baseline. +These can be had at discretion. + +Diagonal fractions +------------------ + +A limited set of diagonal fraction substitutions are available at discretion. +The set is more than what is encoded in Unicode. +They work with the ASCII slash or the mathematical slash U+2215. +The transform a sequence "number-slash-number" to a diagonal form. + +Zero +---- + +A slashed form of the numeral zero is available at discretion. +Available in all faces. + +Alternative characters +====================== + +FreeSerif has some listings of alternatives for specific characters. +Again this is use primarily in specialized typesetting software. + +Greek, Latin + +Use in LaTeX +============ +It is possible to use Unicode fonts in recent LaTeX implementations, but in + LuaTeX http://www.luatex.org/ and + XeTeX http://tug.org/xetex/ +it is particularly easy to use Unicode text, and to enable font features. +Recent versions of these systems use the 'fontspec' package to choose fonts +and features. + +A very simple document might contain the lines +--------------------------------------------------------------------------- +\documentclass{ltxdockit} +\usepackage{fontspec} +\usepackage{xunicode} +\setmainfont[]{FreeSerif} +\begin{document} +{\fontspec[Script=Default,Fractions={On}]{FreeSerif} +1/7 3/10 7/10} + +x\raisebox{-0.5ex}{{\scriptsize ai}} +x{\fontspec[Script=Default,VerticalPosition={Inferior}]{FreeSerif} +abcdefghijklmnopqrstuvwxyz+−(0123456789)} \\ +x\raisebox{0.85ex}{{\scriptsize ai}} +x{\fontspec[Script=Default,VerticalPosition={Superior}]{FreeSerif} +abcdefghijklmnopqrstuvwxyz+−(0123456789)} + +{\fontspec[Script=Latin]{FreeSerif} +\textsc{Small Caps} } + +{ Bсички хора се раждат свободни и равни по достойнство и права. +\fontspec[Script=Cyrillic,Language=Bulgarian,Variant={1}]{FreeSerif} \selectfont +Bсички хора се раждат свободни и равни по достойнство и права. } + +\end{document} +--------------------------------------------------------------------------- +Here are some 'fontspec' setting-value pairs meaningful for FreeFont. + +Numbers: Lining OldStyle Proportional SlashedZero +Fractions: On +VerticalPosition: Superior Inferior +Ligatures: Common Historical +Letters: UppercaseSmallCaps +Variant: 1 (etc. -- must be in {} picks style set.) +--------------------------------------------------------------------------- + + +$Id: usage.txt,v 1.10 2011-07-16 08:38:06 Stevan_White Exp $ |
