[Tex/LaTex] Problem with small caps in XeLaTeX

fontsfontspecsmall-capsUbuntuxetex

I'm not able to make small caps work with any font in XeLaTeX. Here is output illustrating the issue for Charis SIL, Garuda, and Times New Roman, respectively. Pasted below are a MWE and version and package information.

Minimal working example:

\listfiles

For Charis SIL, try using Renderer=ICU. From this mailing list post

Charis SIL is a hybrid OpenType/Graphite font, in 0.9998 OpenType was chosen but in 0.9999 Graphite is chosen instead (a side effect of using HarfBuzz for both OpenType and Graphite) I’m not yet decided whether to consider this a bug or a feature.

Either way, with such hybrid fonts it is always better to be explicit about what font technology to use, adding a “Renderer=ICU” will force OpenType layout (should be renamed “Renderer=OT” now, but it still works nevertheless).

The version of Times New Roman included with Windows XP does not have any small caps, the version in included with Windows 8.1, though, do have small caps and works just fine with XeTeX (no idea about other versions of the font).

No idea about Garuda, though.

[Tex/LaTex] Best free Baskerville font with small caps

Unfortunately, I only know of Open Baskerville and it doesn't have small caps. That said, since it is open-source, you can easily create small caps from capitals using fontforge:

Open the otf file with fontforge ;
Select all capital letters ;
Go to Element -> Style -> Add small capitals
Generate a new OTF file (File -> Generate fonts).

You can then use it with fontspec:

\documentclass{scrbook}

\usepackage{fontspec,xunicode}
\setmainfont{OpenBaskerville0.0.53}

\begin{document}

This is a text in \textsc{Open Baskerville} using \textsc{Small Caps}.

\end{document}

which gives:

[Tex/LaTex] Fake small caps with XeTeX/fontspec

Here I compare an alternative to Yan's approach. I label his method "fake" as he did and label this approach as "faux". I have found (see Good small caps font to use with arev?, for example) that an unequal scaling of horizontal and vertical dimension is better able to capture the proportions of small caps. For Minion Pro, shown in this example, I use 83% horizontal, and 72% vertical scaling to create faux small caps, with 100% horizontal scaling (no change) on the sc Caps. By comparison, I use 91% horizontal and 75% vertical scaling on Computer Modern, with 111% horizontal scaling on sc Caps, and on Palatino, 76% horizontal, 68% vertical scaling, with no change on the sc Caps.

In addition, my \fauxsc macro is able to automatically differentiate lower-case from upper-case arguments, and render them appropriately, which eases the input syntax.

In this MWE, I compare both "fake" and "faux" small caps to the real McCoy for Computer Modern, Minion Pro, and Palatino, respectively.

EDITED to handle UNICODE inputs in Xelatex. Previously, I detected lowercase by seeing if ˋ#1 was in the ASCII lowercase range. This, obviously does not work for UNICODE. Therefore, I adapted macro \fauxschelphelp to test for lowercase-ness using \lccode.

Result can now be seen in last line.
