CREATE DOMAIN idcode AS text

NOT NULL CHECK (VALUE ~* '^\w[-:\w]*$')

;

SELECT 'AAAAAéaaaaa'::idcode; // -> SQL Error: ERROR: value for domain
idcode violates check constraint "idcode_check" (note the accented “e”
between all the “A”s)

This is running just fine against a 9.0 install on the same machine. [\w]
is Unicode aware and server encoding is set (and confirmed via SHOW) to be
“UTF8”.
