As designed Help page URL portion must be a-z

[refael]

Just noticed that the URL portion field of a help page has a note "You may use a-z, 0-9, _ and - characters only".
If your site's main language isn't English, you probably will want to use a name written with your language for more friendlier url.
I guess we can workaround that by creating a route filter (though I didn't test that), but that will just be double work.

Edit: I just saw that this field exists to nodes as well with the same conditions.

This is as designed and you'll find in in most other places where the value entered is the key in the URL. This is done to ensure that character set and URL encoding issues don't cause unexpected problems.
