It is not implementation-defined in C99 whether Unicode characters are accepted; only how they are encoded directly in the source multibyte character set. Characters escaped using \uHHHH or \U00HHHHHH (H is a hex digit), and that are in the sets of characters defined by Unicode for identifiers, are required to be supported, and should be mangled in some consistent way by a platform's linker. There are Unicode text editors which encode/decode \u and \U on the fly, so you can treat this essentially like a Unicode transformation format (it would have been nicer to require support for UTF-8, but never mind). C99 6.4.2.1: # 3 Each universal character name in an identifier shall designate a character # whose encoding in ISO/IEC 10646 falls into one of the ranges specified in # annex D. 59) The initial character shall not be a universal character name # designating a digit. An implementation may allow multibyte characters that # are not part of the basic source character set to appear in identifiers; # which characters and their correspondence to universal character names is # implementation-defined. # # 59) On systems in which linkers cannot accept extended characters, an encoding # of the universal character name may be used in forming valid external # identifiers. For example, some otherwise unused character or sequence of # characters may be used to encode the \u in a universal character name. # Extended characters may produce a long external identifier. -- David Hopwood <[EMAIL PROTECTED]> -- http://mail.python.org/mailman/listinfo/python-list
