Arabic and some other alphabets are not supported in external SRT subtitle formats.
To display external subtitles in Arabic or other, please use the following formats:
- IDX (VOB Sub),
- .sup / PGS (Blu-ray subtitles)
As IDX and PGS are picture based subtitles, it is 100% stable and correctly displayed even with complex alphabet.
To convert SRT subtitle to IDX, we advise you to use Txt2VobSub software available here:
