AFAIK, the big new feature of tcl/tk 9.0 is intended to be full unicode support. We can hope that 9.0 appears in time to be included in the 3.8 installers. Until then, I think filenames, user program output, and clipboard content should be checked for the presence of astral characters before being sent to a tk widget. For this issue, that means replacing the built-in <<Paste>> handler. Replace astral chars with \U000nnnn escapes. If the widget it a Text, tag the escape as 'Astral' and color it with the code context colors to distinguish it from escapes originally in the string. Strings know their kind, but a request to expose that has been rejected. Pyshell currently compares the max codepoint to 'ffff'. But it appears that we can detect kind with an O(1) expression. For 3.6 and 3.7, "sys.getsizeof(s) == 76 + len(s)". For 3.8, "sys.getsizeof(s) == 48 + len(s)". Does anyone know why the difference? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue13153> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
