UTF8 characters in Spotify user id

[zzzrod]

Some API endpoints require the Spotify user id, one example being the "Create a playlist".

I have noticed that some users have special (UTF-8) characters in their ID. Example:

`débug`

When I make an API call with that Spotify user ID, I get an error saying that the user id should be in ASCII. An example from the create a playlist endpoint:

`URI::InvalidURIError: URI must be ascii only /users/d\u00E9bug/playlists`

I have attempted to make the request with `debug`, translating to `/users/debug/playlists` but I'm then hit with an error saying that I cannot create resources in a different user's account.

What's the expected format in this case, especially considering that not all UTF8 characters may have a corresponding ASCII code?

Thanks
