Hi! Welcome to SqueakDBX. We hope we can help you :)
You say "and finally I was able to get my first result". Did you have any
problem? We would love to know it so that to fix it or at least to document
it. We want to make our wiki the most useful possible.

mmmmm  I have a couple of cuestions about this:

1) The database is also in a Windows? or other OS ?

2) Can you send me an example of those czech characters ? perhaps a record
of the user table?

3) I remember that in Oracle you can specify the encoding of the database.
which is the encoding of the one you are trying to use?

4) Can you perfectly send queries and inserts using czech characters  using
a SQL client like sqlplus or SLQDeveloper ?

This is weird. Cannot do it right now, but in case we don't have a unit test
for this, I will do it and see if I can reproduce it here. If there is a
bug, it will be fixed :)

Sorting for sure. Perhaps there is a little bug but this is supported.

National character, I have to investigate it a bit. There are several
"things" here:

- Database support
- Native C client library support
- OpenDBX
- Squeak has a lot of problems with encoding yet
- SqueakDBX

However, my latin amercian characters like:

'éçèéçè',
 'éçèéçèéçèéçè', '
'äöüäöü'
'äöüäöüäöüäöü'

are working well.

When you answer me your questions I can ask openDBX author and also make
some tests.

Best,

Mariano
