Characters allowed in Taxonomy / Category name :?:

I’ve noticed that I can’t use the slash / inside a category name, but can’t find the corresponding naming rules.
Can someone tell me exactly what are the characters we can’t use?

I’m using CS ActiveSOA

Basically you can’t use the slash “/” for naming a category. This is the only character that is rejected.

Best regards,


Thanks Thorsten!
