By opening the font file using FontDrop (https://fontdrop.info), you can see that it supports 39 languages:
Afrikaans Albanian Azerbaijani Belarusian Bosnian Bulgarian Catalan Croatian Czech Danish Dutch English Estonian Finnish French German Hungarian Icelandic Italian Latvian Lithuanian Macedonian Maltese Norwegian Ossetic Polish Portugese Romanian Russian Serbian Slovak Slovenian Spanisch Swedish Turkish Ukrainian Uzbek Vietnamese Zulu
Looks like apart from standard Helvetica/Apple/Microsoft fonts there’s a very small choice of fonts you can use if you have multi lingual UI.
It’s like creating a Latin font is relatively easy, but very few of them go all the way to full Unicode support.
