I like one regexp match more than several substring comparisons. And I didn't want a "huge" array in my code. Just one "simple" regex. My module for matching region codes and international country codes is 9K while the region codes alone are 32K.

32K is not a huge size nowadays, but I'm dated back from the ages of the C64 ;-)

Your solution is quite clever but would need some enhancements to provide for

  1. Different minimal lengths of region codes
  2. Different maximum lengths of region codes
  3. It sholud find those values on it's own
s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e
