Greetz. I find that when a Roman-based fontspec mapping is used in a chapter title or a ToC entry in a memoir document, it causes an error if the input text (not the output) offends (Xe)TeX in some way; thus, `kR^ishhNaM vande jagadgurum.h' (which should simply be rendered as कृष्णं वन्दे जगद्गुरुम्) causes a problem because (Xe)TeX thinks `R^i' can only occur in math mode. Other input texts do not seem to cause such a problem, and the same string also causes no problem inside a chapter (only in chapter titles and ToC entries).
See the attached minimal example, which uses the xetex-itrans package from
CTAN, as well as the Code2000 and Latin Modern families of fonts. The file
should compile cleanly as given, but when the text enclosed inside the \eat{
... } is brought out by commenting out the macro invocation, the problem will
appear.
Any help appreciated. Thanks in advance.
