LDAP - special letters - can't login to Hue

I installed Hue 4.10 in dev server and configure it with LDAP. And after that I can login successfully with my account but some users cannot. I search why they cannot to login to Hue using his/hers domain user account. When they have special letters (for example polish letters like: ą ł ó etc.) in their first name or last name they cannot login to Hue.
This problem is so big for us that we must install an older version of Hue. In version 4.3 this problem not existed so we must use this one, but it is an old version and have some bugs and we want to use the newest one but we cannot.
I write about this on github and also see others that have also problems with that:
