Problems using Korean domain URL

Please understand that I am using an interpreter because my English is not good.
I am making a game with WebGL, and I need to change the existing general English domain to Korean domain.
(ex. aaa.com -> 한글한글.net)
In this case I would like to check if there is a problem when loading Unity or using Post in UnityWebRequest.
If you know about this, I would appreciate an answer.
