This is why text looks wrong in parts of the game and on the website.

Many years ago, VRChat discovered bugs in their user interfaces, but something went wrong and those bugs were never comprehensively fixed. As a workaround, the input sanitization filter was intentionally set up to replace individual characters with full-width or lookalike characters. This affects user statuses, bios, personal notes, world descriptions, group descriptions, group rules, group announcements, and maybe other places.

Over the years, feedback threads have been made about this:

https://feedback.vrchat.com/bug-reports/p/text-is-converted-to-incorrect-symbols-on-upload was marked complete, with Tupper adding "This is intentional and is typical string sanitization. It is done to avoid odd style bugs with UI in the app or on the website."

https://feedback.vrchat.com/website/p/slash-in-a-world-description-turns-to-an-invalid-symbol was marked as tracked as a bug report, but that's the wrong bug to investigate.

Some other similar or dead duplicate threads:

I think it's worth it to investigate and address the original issue(s). Please reconsider giving this more development time, and please consider making the filter less obtrusive for players that have not done anything wrong. Thank you very much!
