400 Client Error: Bad Request for url

[ibLeDy]

I've been using Twitch-Python the same way for almost two months, this is the first time i face this issue. Seems a bit weird as it only happened this one time

helix = twitch.Helix(client_id=CLIENT_ID)
user_data = helix.users([user_name])[0]

user_name is always message.user.display_name.lower()

Traceback (most recent call last):
  File "/home/bledy/projects/barbota/barbota/twitch_chat.py", line 574, in check_user_exists

I suppose the display name has non-latin letters. Use the user's login name instead of display name when calling the api.
