Characters with diacritics/accents are removed from tags. Feature or bug?

[xax-git]

Czech, Slovak, Polish ... special characters with diacritics are removed from Tags, but Evernote as well as Obsidian supports it.
Characters like "ě š č ř ž ý á í é" are removed from tags.
Is it possible to configure somewhere Yarle to not do it?

I encountered the exact same problem where all the Traditional Chinese characters in the tags were removed.
