I realised that this not only applies to compilation with Xe/LuaTeX which is a good thing -- it also catches cases like small letters missing in most math-script fonts (To fix the description in lib/RELEASE-NOTES, just trim the sentence.) > Without this fix, users might not be aware that their compiled PDF will > not show some characters.

I am afraid that while this change will prevent compilation errors, the result is different from before, so any tests that compare the output (or the tex file) must be adapted. I have a partial fix for the "Xe/LuaTeX with TeX-fonts" problem. The fix prevents compilation errors with luatex and improves he situation a bit for xetex (the difference is, that there is "luainputenc" but no "xetexinputenc" in TeXLive and the standard "inputenc" package currently refuses to work with xetex unless the encoding is utf8). Should I commit the patch or wait? Günter
