[PATCH v5 0/4] MR585: Improve is_gecko_path() for handling non-ASCII characters.
This fixes an issue when the path includes non-ASCII characters. Signed-off-by: Jactry Zeng <jzeng(a)codeweavers.com> -- v5: mshtml: Call UrlUnescapeW() with URL_UNESCAPE_AS_UTF8 in is_gecko_path(). shlwapi/tests: Test UrlUnescapeW() with URL_UNESCAPE_AS_UTF8. kernelbase: Implement URL_UNESCAPE_AS_UTF8 for UrlUnescapeW(). shlwapi/tests: Test UrlUnescapeW() with independent data. https://gitlab.winehq.org/wine/wine/-/merge_requests/585

Please don't do checks like that. You may just call `UrlUnescapeW` with a simple UTF8 test case before entering the loop and if it's broken, print `win_skip` and skip UTF8 tests in the loop. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/585#note_41331
