Username with emoji truncated when viewing post

[MetaflameDragon]

Describe the bug
On Android, when viewing a post, certain usernames with an emoji at the end become truncated.
Currently, the only account cursed with this that I could find is dholms.xyz, "daniel 🫠" at the time of writing.

To Reproduce
View a post made by the user. Their username will truncate the last emoji. Again, this only happens for very specific usernames, e.g.
"daniel 🫠".
Reply or parent posts don't have this issue, this only happens for the username on the currently viewed post.

Lovely. Thank you for the solid report!

I did a little bit more investigation, and it confirmed my suspicion that it's to do with emoji added in Unicode v14.0 (and later). A bit lengthy, but I tried to be thorough.

A common symptom is that these emoji show up as crossed boxes in the input field when changing my username. This one (below) was supposed to be 🫶. This isn't specific to skintone-modified emoji, e.g. 🩷 had the same problem.

This resulted in truncation like in dholms' case.

This happened even with emoji or text further in the name.

And as an added bonus, this seems to cause issues on the profile screen too. I filled my username with beans for this one. (Note that the profile screen only shows 3 beans emoji, not the full 8)

I suspect that the text element might be calculating the expected width incorrectly specifically for the newly-added emoji, and not allocating enough space for truncation to not happen?
