Persian subtitles in YouTube

[jamshydf]

I just re-found the old groups.google.com/forum/#!forum/persian-computing so I repeated this question there. with apologies.

I have a question on Persian subtitles in YouTube. For my new YouTube clip which is in Farsi, I wanted to also put Farsi subtitles. The problem is the input shows correctly in the YouTube Studio editor but when I publish it, the subtitles on the actual clip are showing some Farsi letters in unicode isolated form rather than the medial, initial or final forms that they should automatically take in the middle of the word. I tried many ways. first I created a .srt format text file for English and it works perfectly - as you can see on the clip. I then tried the same with Farsi UTF-8 with and without BOM, tried direct input, etc., and none of them work. Any advice? 1/2

2/2 By the way, I'm also having the same problem in MS Word with the font Arial Unicode MS. Doesn't automatically take correct positional form. If you watch my video, the first Persian subtitle looks correct but that's because I typeset it manually in Unicode - so you can make it work but it's not automatic.
