Are slugs still required?
I always used to transform major information of an entity (e.g. title, name) with a slugifizer to a slug which doesn't contain spaces, special chars etc.

Now I accidently forgot the slugifizer and it worked too even with spaces.

Is a slug still required in this time?

Except for IE users of course...

Regards

PS:
I don't want to start a discussion about this topic. I just want to know if all modern browsers (and backends of course) can handle all problems a not-sluged value could cause.
