The following two minimal XeLaTeX examples (using TeXShop 2.37) produce the
indicated problems:
*** Example 1, minimal example:
%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode
\documentclass[draft]{memoir}
\usepackage[no-math]{fontspec}
\newfontfamily\myGeor[Script=Georgian]{BPG Paata Ingiri Vera Unicode}
\begin{document}
\end{document}
*** End of example 1
This example produces the following console output:
fontspec warning: Font 'BPG Paata Ingiri Vera Unicode' does not contain script
'Georgian'.
(fontspec) 'Latin' script used instead.
fontspec warning: Font 'BPG Paata Ingiri Vera Unicode' does not contain script
'Latin'.
(fontspec) 'Latin' script used instead.
..... [repeating the preceeding warning numerous times, and then one final one:]
fontspec warning: Font 'BPG Paata Ingiri Vera Unicode' does not contain script
'Latin'.
(fontspec) 'Latin' script used instead.
./r10n-test.tex:7: TeX capacity exceeded, sorry [parameter stack size=10000].
\use_i:nn #1#2->
#1
l.7 ...pt=Georgian]{BPG Paata Ingiri Vera Unicode}
*** end of console output
The same problem occurs with other fonts that contain neither the requested
script nor Latin script.
*** Example 2, minimal example
%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode
\documentclass[draft]{memoir}
\usepackage[no-math]{fontspec}
\newfontfamily\mytaml[Renderer=AAT]{InaiMathi}
\newfontfamily\mytamlalt[Renderer=AAT,Ligatures=Rare]{InaiMathi}
\begin{document}
\end{document}
*** End of example 2
This example stops with the following console output:
./r10n-test2.tex:8: Undefined control sequence.
<argument> \intexpr_if_even:nTF
{4}{\tl_set:Nx \l_tmpb_tl {\XeTeXselectornam...
l.8 ...alt[Renderer=AAT,Ligatures=Rare]{InaiMathi}
?
*** end of console output
Note that the first \newfontfamily command runs OK, but XeLaTeX stops on the
second one.
Specifics: using fontspec 2.1b and XeTeX 0.9997.4 (TeX Live 2010) running on
Mac OS 10.6.4.
Both examples ran to conclusion (i.e., only producing a warning message in the
first case, and both examples typeset successfully) under fontspec v1.18 and
XeTeX 0.9995.2 (TeX Live 2009)--although as I look at the output again, the
rare ligatures were not actually produced, so I will have to look at the font
again. At any rate, with fontspec v1.18, the syntax was acceptable.
Thanks!
