I think this should probably be fixed. The `ct` buffer is not the full length here - it is just 100 characters long. Although the buffer should not be able to exceed that size given the current possible values for `s->service`, I'm not too comfortable calling `MultiByteToWideChar` with an incorrect length for the output buffer.

Also, it is a little strange to me that this function uses `git__utf8_to_16` here since there are already 4 direct calls to `MultiByteToWideChar` earlier in the same function! It seems like it might be safer to just convert this to directly call `MultiByteToWideChar` and use the actual buffer size for output.
