Xi wants to experiment with using xi/drag person-independent pronouns on this account. So far xi likes using the pronouns, but xi's only written 4 comments and already someone accused drag of talking about Chinese politics when xi mentioned dragself. Xi knows xi's pronouns are confusing, so xi would like to put xi's pronouns in xi's displayname to clear things up.
But the character limit for display names on lemmy.nz is only 22 characters, and xi's handle already takes up 16 characters. Xi would need 24 characters to put xi's pronouns in xi's display name. Xi knows some instances also have a separate field for pronouns, and the pronouns get displayed next to the name without taking up displayname characters. Xi would like a place, or at least enough room, for xi's pronouns, please.
Hey sorry I've had a play and it doesn't look like this is a configurable setting in Lemmy.
Lemmy.nz runs the Lemmy software, but we don't develop it. I suspect the limit is set that low on purpose, though. Mobile screens are not that wide, and there's a lot of info to display for every comment, so it would need to be quite small to account for that. Note that not all people we interact with on Lemmy are using Lemmy software (e.g. they could be on instances using Mastodon, Kbin, Mbin, Piefed, etc), so different users may have different restrictions.
