I use Bengali font/language on my site. And its old blog. Now the issue is, my post permalink are this: website/blog-post-name

As I use benglai, the permalink are looks like this: website/blog-post-n

Thats mean part of the name are broken. I know there have some limits on permalink like how many character can be there. As its unicode font, word are more then its limit.

So wanna know how can I increase the limits as its looks really bad with broken permalink.
