Ice OCCI demo

There is an occi demo in Ice release.
It works fine but I have a question.
What should I do if database have different character set?
All characters that aren't in English displayed as question marks.

I found a solution.
I should make OCCI environment like this:

_env = Environment::createEnvironment("UTF8", "UTF8", Environment::Mode(Environment::THREADED_MUTEXED | Environment::OBJECT));
