This seems like the best VR 3D video player out there, but sadly subtitles are missing international support.
Here in Czechia we usually use windows-1250 encoding (ANSI), but I don't see some special characters like "š" - it looks like they are skipped in the text. There are some efforts to use UTF-8 as default by some, but currently UTF-8 encoded SRT files are skipped as invalid. I found out you can convert the subtitles to UCS2LE or UCS2BE and they show correctly.
I think there should be a new global option to choose default font encoding. UTF-8 with or without BOM should be recognized automatically and valid.
Also if I add new subtitle files while the player is running, I don't see them in the subtitle selection menu unless I restart the player completely. Closing and reopening video doesn't help.
