The Greek combining koronis, U+0343, is an allowed identifier character and also looks identical to a single right quote, U+02BC = U+0313 = U+0315 = U+0343 = U+2019. > U+0312, U+0313, and U+0315 are combining characters that cause the > comma to appear over the preceding letter, and they are not allowed > to appear as the first character in an identifier.

I just realized that this is not the whole story. There's no requirement that a combining character has to actually come after a character it can be combined with. So there might be valid identifiers containing sequences of characters that don't have a sensible rendering, or that force the combining comma to appear separately and thus indistinguishable from a quotation mark even in a Unicode-aware editor. -- ?!ng _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
