Hi,

Thanks for your help. The function octet_length() is available at 2.0
or higher I think, so I can't run that query. Are there any similar
function in FB 1.5?

In the other hand, supose query confirms that data is in utf8 format.
How can I solve the problem? I would manage data from linux boxes (as
maintentance) and windows boxes (for import data in this case). Data
is introduced from an php application (in a debian box), so I think
it's written in utf8 format. What about if I change database domains
and default charset to utf8? Would it permit read from windows without
problem?

Thanks again.
