I cannot find any documentation which says exactly which non-ASCII characters IronPython will accept. I would guess that it probably follows C# in general, but it doesn't follow C# identifier syntax exactly (in particular the leading @ to quote keywords is not supported). The C# identifier syntax from http://msdn2.microsoft.com/en-us/library/aa664670(VS.71).aspx I think it differs from the PEP only in also allowing the Cf class of characters: identifier: available-identifier @ identifier-or-keyword available-identifier: An identifier-or-keyword that is not a keyword identifier-or-keyword: identifier-start-character identifier-part-charactersopt identifier-start-character: letter-character _ (the underscore character U+005F) identifier-part-characters: identifier-part-character identifier-part-characters identifier-part-character identifier-part-character: letter-character decimal-digit-character connecting-character combining-character formatting-character letter-character: A Unicode character of classes Lu, Ll, Lt, Lm, Lo, or Nl A unicode-escape-sequence representing a character of classes Lu, Ll, Lt, Lm, Lo, or Nl combining-character: A Unicode character of classes Mn or Mc A unicode-escape-sequence representing a character of classes Mn or Mc decimal-digit-character: A Unicode character of the class Nd A unicode-escape-sequence representing a character of the class Nd connecting-character: A Unicode character of the class Pc A unicode-escape-sequence representing a character of the class Pc formatting-character: A Unicode character of the class Cf A unicode-escape-sequence representing a character of the class Cf For information on the Unicode character classes mentioned above, see The Unicode Standard, Version 3.0, section 4.5. -- http://mail.python.org/mailman/listinfo/python-list
