title: How to find special characters in DB2?
body: <p>I have a DB2 database containing millions of records.
  I found that some char() or varchar() fields contain special characters which shouldn't be stored.
  I guess application received broken data or some code made it.</p>
  
  <p>Anyway, I want to find records that have these broken data, which are special characters (not alphabetic).</p>
  
  <p>I tried to find the way using query but couldn't.
  Does someone know the good query or advice?</p>
