[bug] problem with using of non-english characters in tags

[utkonostracker]

This torrent https://demo.sqtracker.dev/torrent/0027b9df8f1a7ff500982a65feb7bfe86d4276f1 has the same string as description and tags.

We can see that while description is showing everything correctly, tags are messed up.

Currently:

1. Tags written in Chinese, Japan and Korean languages are imediately removed upon pressing "Save changes". This means that we will get empty spaces instead of tags and if we will try to edit torrent again there would be just commas.
2. Tags written in Greek, Persian, Arabic, Russian and French languages are imediately transliterated upon pressing "Save changes".

So for now only English tags could work flawlessly.

Expected:

1. All tags should be saved correctly, as they are written in their original language.
2. All tags should be shown correctly on torrent description page, as they are written in their original language.
