Routine to trim Unicode data to a size that will fit in a fixed length field ...

... that may or may not include double byte.

After going back and forth on a routine to trim a Unicode string to a length that will fit into a fixed length database field, I came up with this routine ...

You call it with a Unicode string, the field size in question, and the CCSID of the field, and it will return a Unicode string that has been trimmed to a length that will completely fit in the database field. Alternatively you can call the method with an AS400Text field object and it will get the length & CCISD automatically.

Basically, the routine uses the CharConverter class to convert the Unicode data to double byte, trims the double byte to fit into the field length, and then checks to see if the so/si pairs are balanced. If they are not balanced it balances them ... then converts the trimmed value back to Unicode .

It requires the Apache Commons Language utilities. You'll probably want to substitute your own logger function, or have it throw the encoding exception.
