The following transact SQL script works for all languages (international). The solution is not to check for alphanumeric but to check for not containing special characters.

DECLARE @teststring nvarchar(max)
SET @teststring = 'Test''Me'
SELECT 'IS ALPHANUMERIC: ' + @teststring
WHERE @teststring NOT LIKE '%[-!#%&+,./:;<=>@`{|}~"()*\\\_\^\?\[\]\'']%' {ESCAPE '\'}
