Whether or not the Tcl developers were explicitly following this advice, the routine in Tcl 8.1 for decoding Unicode codepoints from the encoded byte sequences, > **int** **Tcl_UtfToUniChar** ( **const char** *_str_, **Tcl_UniChar** *_chPtr_), implements the same forgiving support for overlong byte sequences.
