Emojis as usernames don't work
I tried using 🐄 as a username on oddmuse.org but it got replaced with “Anonymous”. Seems to be a fairly old issue because on one of my private wikis there's an identical issue.
We definitely need a better regular expression for valid page names. That’s the main problem. And we don’t want to allow just anything since user names = page names = file names. So we need to look at limitations of the system. No slashes, no null bytes. Ideally, we would use something like “all printable characters” for the Unix family of file systems (ext3, ext4) and relegate problematic filesystems to modules like HFS issues which got relegated to mac.pl. Then we no longer have to worry about forbidden characters and directory separators in NTFS and HFS and all that.
