VLC should not display RLM and LRM in subtitle files
Many SRT files may contain right-to-left marks (U+200F) or left-to-right marks (U+200E) if it contains bi-directional text. VLC behaves in the expected manner when it encounters these characters (the direction of text flow is altered correctly), but VLC display a character onscreen for these marks.
Instead, VLC should display nothing at all for these characters, not even an empty space. They are essentially control characters.
