If i enter Japanese in "profile_name" on the profile change screen, an error will occur.
"The User Name you have entered is already being used by another account."
This phenomenon always occurs when the user inputs in Japanese, but there is no problem when accessing as Admin.
Which specification is correct for this?
My hope is that "user_name"and"profile_url" should be a-z,0-9,-, but I would be happy if "profile_name" could be in Japanese.
I am not good at English. I do not really understand scripts like PHP. Please forgive me. It is difficult to find information on JAMROOM in Japanese.
