In this example, assume that the default server character set is UNICODE. The values of the Description column are compressed using the TransUnicodeToUTF8 function with ALC, which stores the Unicode input in UTF8 format. The TransUTF8ToUnicode function uncompresses the previously compressed values.

CREATE TABLE Pendants
   (ItemNo INTEGER, 
    Gem CHAR(10) UPPERCASE,
    Description VARCHAR(1000)
       COMPRESS USING TD_SYSFNLIB.TransUnicodeToUTF8
       DECOMPRESS USING TD_SYSFNLIB.TransUTF8ToUnicode);
