Incorrectly decoded strings in Repository.path and Repository.workdir when using Python 3 on Windows

Example:

>import pygit2
>import sys
>r = pygit2.init_repository(r"C:\repösitory")
>r.path
'C:/repösitory/.git/' # this is a wrongly decoded path
>r.path.encode(sys.getfilesystemencoding()).decode("utf-8") # workaround
'C:/repösitory/.git/' # this looks right

Reproduced with "pygit2-0.28.2-cp35-cp35m-win32.whl".

The problem seems to be in "repository.c", function "Repository_path__get__":

return to_path(git_repository_path(self->repo));

The "to_path" function assumes that libgit2 returns a byte string with file system encoding:

#define to_path(x) to_unicode(x, Py_FileSystemDefaultEncoding, "strict")

But libgit2 actually returns a byte string encoded in UTF-8.
Maybe the behaviour of libgit2 has changed at some point?

Reproduisez l’exemple Python 3 sous Windows avec un chemin de dépôt contenant des caractères non ASCII, puis examinez repository.c, en particulier Repository_path__get__ et la définition de to_path. Vérifiez à la fois Repository.path et Repository.workdir, et assurez-vous que les chemins renvoyés conservent les caractères d’origine sans le contournement documenté.
