annotate src/if_py_both.h @ 2894:fe9c7da98b5e v7.3.220
updated for version 7.3.220
Problem: Python 3: vim.error is a 'str' instead of an 'Exception' object,
so 'except' or 'raise' it causes a 'SystemError' exception.
Buffer objects do not support slice assignment.
When exchanging text between Vim and Python, multibyte texts become
gabage or cause Unicode Expceptions, etc.
'py3file' tries to read in the file as Unicode, sometimes causes
UnicodeDecodeException
Solution: Fix the problems. (lilydjwg)
