When creating a topic, the url is formed in the form example.com/t/topic/39/ - there is no conversion of the Cyrillic alphabet from the title to Latin letters. But, if the title contains a word in English (in this case Ruby), then it necessarily appears in the url example.com/t/ruby/36 If 2-3 words are in English, then example.com/t/erb-vs-code/29, but words in Cyrillic are not converted.
What is the reason for this url formation and how to fix it?
ps forum in Ukrainian. I assumed that the problem was due to some letters - і, ї, є I tried to publish the title in Russian - such a problem. The problem is common to the Cyrillic alphabet.
