Allow special characters in users bio
Created by: jvanbaarsen
What does this do? It removes the very strict sanitation on the users bio field, so that people can have a bio like "I <3 GitLab"
Why is this needed? Currently when you enter a bio with "I <3 GitLab", we only store "I ". This is unexpected behaviour, since we want users to have a normal profile, without having to worry what characters are allowed and which are not.
