The POSIX classes must be used inside a character class:
grep /[[:alpha:]]/, map chr, 0 .. 0xEFFFF;

If running this is too slow, save the result (in a variable, or in a file for persistence).

Update: s/char/chr/, thanks pryrt.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
