Hi Jamshyd,
Re problem 1:
As of 2022, YouTube uses the HTML "video" tag on most platforms, and the subtitle is also rendered via the HTML technology, using a "span" of text.
For example, this is how the video and subtitle are built into the HTML page on a Chrome on MacOS browser:
And, the result is a proper rendering of the CC text on the page, as seen here:
If you have any problems with that text being rendering on a YouTube page, there's a chance that the browser/OS you're using is lacking some latest features, or have some bugs with rendering text. I don't think there's much YouTube can/would do to fix that, either way.
Re problem 2:
It's a known issue with some versions of "Arial" font files from Microsoft. IIRC, they fixed it at some point—probably early 2010s—but I could be wrong. Maybe a search in the archives of Persian-Computing lists would help answering that. Personally, though, I would suggest avoiding using the font for Persian text to start with; the design isn't really worth taking that risk.
Hope you find these helpful,
