... 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 ...
http://code.midrange.com/9c0db304e1.html
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.
