How to set Cyrillic names of html files on hosting?

Question

HTML

I am creating a small site, 4 html pages, with the index everything is clearly not displayed, but the question arises when accessing the remaining 3 pages, let's call them conditionally - one.html two.html three.html. It is not possible to contact them, it throws an error 500 when accessing them. Those. moisite.rf/odin.html - error 500, moisite.rf/odin.html - everything is clear
Cyrillic in the title is necessary, so transliteration or translation is no longer an option.
Thanks for answers.

Answer 2

You can configure url interception on the server, it all depends on the solution stack you use:
For apache, mod-rewrite is usually used, writing the settings in .htaccess;
At the framework level (like rails, express or yii), it is enough to properly configure the routing module.
