Random character from other language appearing in ASR subs

I use ASR in the media file player to to watch some arabic stuff. Very rarely (like once every 2 weeks) there are random characters that popup in the arabic generated subs. All of the times this happened it would be hebrew letters but this time I got one in russian

Look at the leftmost character in the arabic subtitle, the inverted N I believe is russian

This never happened for this exact phrase before
