What were you expecting to happen and what in fact happen?

According to help, name of the repo should "only contain characters A-z, numbers and underscores", so when I used names with characters that aren't one of those to fail, but instead it turned out that I can freely use space, hyphen, dollar sign, etc.

How can we reproduce this issue?

Just try adding repo with name that contains some other characters, for example test$2
