I use portuguese language and proceed the following way:
1. set the DB_LOCALE, SERVER_LOCALE and CLIENT_LOCALE environment variables to "pt_br.8859-1" (without the quotes);
2. Create the database;
3. Use nchar or nvarchar data types in the columns I want to sort, instead of char and varchar.
This works for portuguese. Look in the $INFORMIXDIR/gls directory what code corresponds to your language. You can check if your database was created in your language using the following SQL command in sysmaster database:
select * from sysdbslocale;
It will give you a list of all your databases in the instance and the respective language.
I hope it will help you.
Fernanda.
