Xbox One: SRT subtitle doesn't autoload and Chinese characters displayed all as rectangles
My test video has an external subtitle file which is in the same location as the video file and is the same filename with .srt extension. When I tried to toggle subtitle on, it shows no subtitle message. After trying few times found out there's a way to manually load it and it is successfully loaded, English text displayed properly but the position is a little bit too high and all Chinese characters are displayed as rectangles.
Note: test video is MKV, video is AVC L4, 8k bit rate, 1920x800, 23.976 fps audio is DTS Subtitle file is UTF-8 format.
