CP1250 to and from Unicode conversion, how?

Hi all.

I have a database with text fields containing text with Windows CP-1250 encoding. How can I convert it to Unicode? I
havebuild the database with 

--enable-recode              enable character set recode support
--enable-multibyte           enable multibyte character support
--enable-unicode-conversion  enable unicode conversion support

Also, how can I enter a string containing Unicode chars from "psql"? What is the Unicode escape sequence?

I mean, if all else fails, I'll dump database, run the dump through script/Java/C program to convert all CP-1250 chars
totheir Unicode equivalents and import it again. 

Hope someone will answer my question.

Nix.
