The URL parser encodes the input path to a URL-encoded path even if it is local, so if the path contains unicode characters (such as Japanese Kanji ), the media file cannot be read.

Following workaround works :


	FString FURL_RFC3986::Get(bool bIncludeQuery, bool bIncludeFragment)
				if (Authority.Len() && !IsPathSeparator(Path[0]))
					URL += TEXT("/");
#if 1	//work around
				if( Scheme.Equals(TEXT("file")) )
					URL += Path;
					UrlEncode(URL, Path, RequiredEscapeCharsPath);
				UrlEncode(URL, Path, RequiredEscapeCharsPath);
			else if ((Query.Len() && bIncludeQuery) || (Fragment.Len() && bIncludeFragment))
				URL += TEXT("/");

Steps to Reproduce
  1. Extract attached repro project  [Link Removed]
  2. rename project folder name to "MyProjectテスト" 
  3. open the project
  4. start PIE session
