Is this a good idea (or at least the 80 characters limit)? While I agree it's usually excessive, there are many cases where someone's full name can be pretty long (e.g., Pablo Picasso, Hubert Blaine Wolfeschlegelsteinhausenbergerdorff (yes, that's the 'short' version)).

Another example: Karl-Theodor zu Guttenberg (the current German politician).

However, whether someone would use their very long full name as a display name, I'm not sure.

Karl-Theodor zu Guttenberg

That's 26 characters

Pablo Picasso, Hubert Blaine Wolfeschlegelsteinhausenbergerdorff

64 characters.

So yeah... I think 80 is sufficient. 😄

@corrideat Its my perception that people with long name usually want to use a shorter version when possible and also often encourage others to do so too.(Who would enjoy typing 80 characters each time they call someone in the chat?)

Karl-Theodor zu Guttenberg

Karl-Theodor Maria Nikolaus Johann Jacob Philipp Franz Joseph Sylvester Buhl-Freiherr von und zu Guttenberg

Pablo Picasso

Pablo Diego José Francisco de Paula Juan Nepomuceno Cipriano de la Santísima Trinidad Ruiz Picasso

Hubert Blaine Wolfeschlegelsteinhausenbergerdorff

This one is over half a KiB

Probably that's what most prefer, yes. But since 80 characters aren't going to fit on screen / the UI component anyhow, it seems like an arbitrary limit.

LGTM!
