[Bug]: Missing Unicode filtering for names? (e.g. RTL override can affect UI strings)

[valpackett]

Describe the bug

A name ending in an RTL Override character results in the UI string "boosted" getting displayed as "detsoob":

This is innocent enough :) but I'm wondering which other Unicode magic could affect things in unexpected ways. Probably would make sense to filter that kind of thing / reset the unicode context somehow (maybe just splitting the user string into a separate label)?

Alice is breaking mastodon web too 😩

Not sure about splitting them into separate labels as it might cause issues with the translations and screen readers. I need to check how desktop notifications handle it too 🤷

Honestly, this feels like something pango markup should already support :/ like <bdi> or even a span with dir set

Apparently trying to isolate this in one text block is non-trivial…
