Yes, up to 0x10ffff should be enough.
The 24 is not really important, this is all about what utf-8 strings to
accept as input. The strings are stored as utf-8 strings and when
processed inside pg it uses wchar_t that is 32 bit (on some systems at
least). By restricting the utf-8 input to unicode we can in the future
store each character as 3 bytes if we want.
