* Name change: better unicode handling Client-side: * Changes the NameChangeModal to show text "Over limit" when a proposed display name is too long. * Allows names to go over limit to prevent splitting graphemes on input. Server-side: * Changes the MakeSafeStringOfLength to count number of unicode code points instead of string bytes. * name modal: check that newName is defined before iterating
