Cannot identify (and extract) Big5 filename

[GoogleCodeExporter]

What steps will reproduce the problem?
1. call archive_entry_pathname_w with a zip file which contains big5 filename
2.
3.

What is the expected output? What do you see instead?
expected: could identify and extract big5 filename correctly
actual result: mbtowc would return fail and EILSEQ when meeting some big5 
characters

archive_wstring_append_from_mbs: 
p=***�ꤤ���D��/SteadyHand/Thumbs.db***
archive_wstring_append_from_mbs: mbs=�(0xffffffb0)
archive_wstring_append_from_mbs: mbtowc failed
archive_wstring_append_from_mbs: is invalid char
archive_wstring_append_from_mbs: mbs=�(0xffffffea)
archive_wstring_append_from_mbs: mbs=�(0xffffffb2)
archive_wstring_append_from_mbs: mbtowc failed
archive_wstring_append_from_mbs: is invalid char
archive_wstring_append_from_mbs: mbs=�(0xffffffd5)
archive_wstring_append_from_mbs: mbtowc failed
archive_wstring_append_from_mbs: is invalid char

In the above example, b0ea (國 in big5) b2d5 (組 in big5), 0xb0, 0xb2, 0xd5 
was considered invalid while 0xea considered valid.

Could you provide us a (small) example archive that demonstrates this problem?

What are your locale settings?

Is this a custom program?  If so, are you calling setlocale()?  With what 
arguments?
