To be clear, some really great community members have these names, but they’re everywhere now. And with the right characters you can create some really annoying overlaps: https://github.com/LemmyNet/lemmy/issues/3790
Enough of them floating around now that I’ll probably do a PR for my favorite client to filter them out.
Some characters that are permitted in the Display Name field can totally mangle the layout of the page on a website or even on an app. Like those letters that have a bunch of random noise attached to them that people like to use to symbolize glitchiness or Eldritch corruption.
I would hope that something like mine, which is just standard emojis, wouldn’t do that since modern layouts account for those. I kind of agree that there should be some limit, just due to the fact some non-standard characters can totally break the site.
