Integrate changes from the japanese community

[jackburton]

The Japanese community (the people at JPBE.net) made some changes to our libtextencoding.so to support their language more correctly. We asked them for the changes and we got them (already some time ago, actually). We should find a way to integrate the patches without breaking anything. I'm including here everything I got from Momoziro.

I also got this link from Momoziro:

And here's the explanation from Momoziro:

The revision part of the unzip only erased "OEM_INTERN((string))" in "Ext_ASCII_TO_Native" macro of trunk/src/bin/unzip/unzpriv.h. The file name broke when the file name (Shift_JIS encoded multi-byte Japanese language characters) was mis-recognized to iso8859-1. I did the change that invalidate the character-code conversion. I think that this is not a good method.
