Hi @Akerhielm! Thanks for dropping in on this conversation. You might want to check out the recently sparked discussion after I spoofed Kroc’s name here on the forum: http://forum.camendesign.com/shuting-down-website-for-a-month+1#1to6h29w2xol

There is now a NoNonsenseForum issue on points 1 and 2, whitespace, we would appreciate all input: https://github.com/Kroc/NoNonsenseForum/issues/175 (Normalising space and invisible characters in names.)

If you know your way around the Unicode specification also check out the issue on validating bytes: https://github.com/Kroc/NoNonsenseForum/issues/176

It is no longer a theoretical problem I am having, but also something we would love to land in the NNF core.
