Lets say i have a category that the url looks like this: https://www.kalosex.com/yiresie-a-%ce%86ntre
normally, i would love it to be something like https://www.kalosex.com/ypiresies-apo-antres which is more close to what it has to be

I use the classic code on .htaccess but still i get this result. Anyone have a solution?

Saw this solution on stackoverflow: https://stackoverflow.com/questions/27191812/urls-in-the-browser-and-language-specific-characters
But not sure where this function should be placed and where to be called.

Thank you very much!
