I have been asked to look into support for sorting non-latin 'alphabets' such as Chinese and Japanese. I am therefore interested in finding out how well DB2 supports sorting of entries for these writing systems and what supplementary configuration I may need to do.

Any links or documentation on the subject, with regards to DB2 would be useful.

For a start, have a look at the CREATE DATABASE command - COLLATING SEQUENCE, CODESET and TERRITORY.

There will be an article on case-insensitive string comparisons coming up shortly on developerWorks. While you have a different problem, there is sample code that shows how to use a user-defined collation sequence in case the DB2-provided collation sequences are not suitable for you.
