   In debug, does ds_NMMLIMP2.ITEMNAME look correct before the %subst? Does
   it have UTF8 data? (look at the hex value of the field in the debugger)

   Does ds_NMWRKR.ITEMNAME8 look correct after the %subst?

   Is it always incorrect? Or does the problem only happen with some values?

   Using %subst with UTF8 data has the potential to only pick up the first
   byte of a 2-byte character unless you are using the new CHARCOUNT NATURAL
   support.

   (I should update that pdf document to talk about the CHARCOUNT support
   that was added in 7.4 and 7.5 with PTFs.)
