Does anyone know offhand whether the Unicode Consortium has an explicit policy against use of punctuation in a charname? So far they only seem to use hyphen and parens, but I wonder to what extent we can depend on that... In any case, STD doesn't currently try to check the string in \c[...] for correctness. It just scans for the closing bracket. We will certainly need to refine this, and the suggested approach is certainly a possible outcome, if we decide it's sufficiently unambiguous. Larry
