Informix GLS Queries...

Dear All, I have created my database setting both DB & CLIENT Locales to utf8. I have a few queries on it - 1. Does the actual data in japanese/chinese language get inserted in the database, how can i view them through dbaccess 2. Will the current width be enough to hold the data in japanese/chinese languages, for eg. i have a name column which stores 20 chars, so when i have to store japanese data will it be able to hold 20 chars or i will have to increase the size of my column. 3. How do i do sorting on a column which has data inserted in many languages, for eg.i have rows in french, spanish, japanese & chinese. How do i select sorting fora particular language, is there an env. variable for it. Please advice. Thanks in advance. Best Regards, Lloyd
