[Tiki-users] Allowed characters in page names confusion

Hi!

I'm wondering which characters are allowed in page names. 

In Tiki for Smarties it's written "In fact, you can use nearly any
character, except & (ampersand), in a page name.":

https://twbasics.tikiforsmarties.com/Using-the-List-Wiki-Pages-page

In this page:
https://doc.tiki.org/Safe-Characters-in-Wiki-page-names
it's written that the following characters are allowed:

: / ? # @ ! $ & ' ( ) * + , ; = < > 

So the slash should be safe. But when I try to create a page with a
slash in its name, I get an error message which states that the
following characters are forbidden:

 /?#[]@$&+;=<> 

I've searched doc.tiki.org for some half hour and couldn't find any
definitive answer...

I'm about to send a bug report to the author of Tiki for Smarties.

Cheers
Volker
