Content
Seems as Tk stores pasted "\U000104a2" as surrogate pair "\ud801\udca2". Then it encoded in UTF-8 as "\xed\xa0\x81\xed\xb2\xa2" end passed to Python. Python converts char* to Unicode object with PyUnicode_FromString() which forbids invalid UTF-8 including encoded surrogates. Please test proposed patch on Windows.
