For what it is worth, IBM APL 2 gives:
⍋'AAA' 'Y' 'BBB' 'CC'
DOMAIN ERROR
⍋'AAA' 'Y' 'BBB' 'CC'
∧
Z←'AA' 'XX' 'AAA' 'XXX'
⎕UCS¨Z
65 65 88 88 65 65 65 88 88 88
⍋⎕UCS¨Z
DOMAIN ERROR
⍋⎕UCS¨Z
∧
⊃Z
AA
XX
AAA
XXXX
⍋⊃Z
DOMAIN ERROR
⍋⊃Z

I have no real preference regarding this. I am just providing this for
informational purposes. Please feel free with other tests you would like
me to perform.
Thanks.
