Add support for wide characters.

[mykhailopylyp]

There are potential issues while using this lib on localized versions of windows. That can happen if a path string has characters that do to fit into char. Anyway, is there a way to deal with it now?

Look at this PR (already merged): https://github.com/kuba--/zip/pull/150/files

The above PR does not address my concerns.
For example, if I want to pass the full path to zip_open I want to be able to pass wchar_t* instead of char* because some windows localized paths just do not fit into char*.

A possible solution - if the preprocessor directive(e.g. USE_WIDE_CHARACTERS) is defined use wchar_t* else use char* so then consumers of that code can decide what they want to use.

But at the end you have to convert them for std. library, so I suppose you can use one of those helpers:

zip_extract doesn't work for UTF-8 characters. I found the problem in zip_mkpath() which calls _mkdir.
If I personally do the MB/WCHAR conversion there and and cll _wmkdir, it works.

I can fix zip_mkpath for windows in similar way how mz_stat was done.

That would be very helpful! Thanks!!
Also, is there a release version coming soon?

[kuba--]

@UAchar - PTAL https://github.com/kuba--/zip/pull/200
...if it works for you.
I can push a new release after we merge the PR(#200). I don't expect any destabilization in recent commits.

Is this issue resolved in the latest release?

[kuba--]

@franky920920 - both PRs (#200 and #150) were merged, so wide characters for fopen, mkdir, are supported since release v0.1.32.

Please, re-open the issue, if it's needed!

@kuba--
It is still not possible to pass wchar_t* to zip_open.

[kuba--]

@mykhailopylyp - yes, there is no public API to support wchar, but just some internal functions on windows.
