Getting patch with unicode characters confuses git apply

var patches = repo0.Diff.Compare<Patch>(commit1?.Tree, commit2.Tree, Enumerable.Repeat(change.Path, 1), compareOptions: compareOptions);

Getting patches + applying them to file does not seems to work if there are unicode characters in file itself.

Have tried to save it in utf8, but problem still persists.

As a walkaround to this problem, I have added extra comparison that there aren't any unicode characters.

// If we have some unicode characters, then cannot be handled as text diff.
canBeHandledAsTextPatch = strpatches.All(c => c <= 255);

But, libgit itself has built in support for patching, See https://libgit2.org/libgit2/#HEAD, git_apply* function calls - but none of these operations seems to be supported in libgit2sharp.

首先通过 Diff.Compare 和现有的文本补丁处理来复现 Unicode 失败问题，然后检查 issue 中引用的 libgit2 git_apply* API。完成标准是：无需使用所述 workaround，即可正确获取并应用包含 Unicode 字符的文件的补丁。
