  1. The session parameter LCU is identical to the session parameter LC. The difference is that the leading characters are always stored in Unicode format. This allows you to specify leading characters with mixed characters from different code pages, and assures that always the correct character is displayed independent of the installed system code page.
  2.  The session parameters LCU and ICU are mutually exclusive.
