[issue10614] ZipFile: add a filename_encoding argument
Sergey Dorofeev added the comment:
I'd like to submit patch to support zip archives created on systems that use
non-US codepage (e.g. russian CP866).
Codepage would be specified in additional parameter of ZipFile constructor,
named "codepage".
If it is not specified, old behavior is preserved (use CP437).
