"Subtitle shows as square" means you are seeing a solid rectangular block instead of characters?

Do you know if the bug occurs in other languages that are read right-to-left?

Here is a screenshot

I should add other player such as xplayer can show it properly.
About other rtl language I really don't know but this doesn't happen on all subs just in this particular video.
Sorry for my bad English.

Yes, I can confirm the issue, same behaviour for me with VLC 3.4.0 RC1 on my Samsung running Android 10.
However it's playing fine with MPV for Android on the same phone. The Samsung built-in video player is also showing correct subtitles but the lines are somehow 'blended' and misplaced.

You should create a new ticket on the VLC Trac with your above report, the link to your sample file and the link to this thread:

VLC has no real font selection on Android
:!: If you want your problem to be solved :
* First read troubleshooting guide VSG:Main
* Always provide verbose LOGS ! (command line or from gui)
* Always check your issue against a developer build from Nightly Build of VLC
* Tell us when your problem is solved !

Well, looks like MPV and the Samsung player are automatically doing this because I'm not selecting any font at any moment.
