It's already implemented; nothing needs to be done. Unicode Standard Annex #31 defines a recommended syntax of identifiers, which Python basically follows, except that for backward compatibility Python also allows identifiers to begin with an underscore. Compare the recommended syntax at http://unicode.org/reports/tr31/#Default_Identifier_Syntax with the Python syntax at https://docs.python.org/3/reference/lexical_analysis.html#identifiers. -- https://mail.python.org/mailman/listinfo/python-list
