 This package is an extension of Bitstream Charter, whose original license is reproduced below, as required under the terms of that license. The extension provides small caps, oldstyle figures and superior figures in all four styles, accompanied by LaTeX font support files. The font files themselves are  in otf and pfb formats. The fonts are licensed as Free fonts under the same terms as the original from Bitstream. All other support files are subject to the LaTeX Project Public License. See

+Changes in version 1.206
+1. Added many new glyphs so that coverage of the TS1 encoding is essentially complete.
+2. Added many new superscript letters and symbols.
+3. Added i.TRK and i.TRKsc with a localization lookup and an added c2sc entry for Turkish language (latn/TRK) users.
+4. Added a new \textcircled macro to the sty file.
+5. Improved the \textfrac macro.
 
 Changes in version 1.205
 Replaced the otf files, some of which had corrupted feature lookups.

-Three math packages seem to provide reasonable companions for \textsf{XCharter}. The first example uses Charter italics as math italics, but doesn't provide arbitrary scaling and doesn't sufficiently distinguish math italic v from mathematical Greek \verb|\nu|. Moreover, it is not easy to redefine \verb|\mathcal| to get a better math calligraphic alphabet---eg, the {\tt mathalfa} package fails. The second uses \textsf{libertine} italics and Greek in math mode, which is a good match to Charter in style and weight after scaling up, is arbitrarily scalable, has distinct math italic v and mathematical Greek \verb|\nu|, and is completely compatible with {\tt mathalfa}. The third is a new revision of {\tt newtxmath} with option {\tt charter} (or, equivalently, {\tt xcharter}), which substitutes Charter italics as math italics and, as of version 1.11,  uses a newly developed family of Greek symbols in \{regular, bold\} $\times$ \{upright, italic\} to match the style and italic angle of XCharter. This version is scalable and has a math italic v (plus a matching w) distinct from \verb|\nu|. (The option {\tt noxchvw} to {\tt newtxmath} changes the v and w to be the original Charter italic glyphs, which may lead to issues with \verb|\nu|. The option {\tt alty} to {\tt newtxmath/charter}, new as of version {\tt 1.203}, substitutes $y$ for the default \emph{y} which, IMO, works better in combination with other math symbols because it lacks the problematic tail of \emph{y}.)

 \section{Text effects under \texttt{fontaxes}}
-This package loads the {\tt fontaxes} package in order to access italic and slanted small caps. You should pay attention to the fact that {\tt fontaxes} modifies the behavior of some basic \LaTeX\ text macros such as \verb|\textsc| and \verb|\textup|. Under normal \LaTeX, some text effects are combined, so that, for example, \verb|\textbf{\textit{a}}| produces bold italic {\tt a}, while other effects are not, e.g., \verb|\textsc{\textup{a}}| has the same effect as \verb|\textup{a}|, producing the letter {\tt a} in upright, not small cap, style. With {\tt fontaxes}, \verb|\textsc{\textup{a}}| produces instead upright small cap {\tt a}. It offers a macro \verb|\textulc| that undoes small caps, so that, eg, \verb|\textsc{\textulc{a}}| produces {\tt a} in non-small cap mode, with whatever other style choices were in force, such as bold or italics.
