Getting wrong output form input of any username with a trailing underscore

Description When inputting usernames (Twitter, Github, Linkedin or Patreon) with a trailing underscore (i.e foo_), a backward slash is inserted before the trailing underscore leading to errors loading the badge correctly and having to manually fix it.

GitHub username (use empty value to skip) foo\_
