Czech2ASCII with --mb=Latin2

Hi,

I have a database in Latin2 encoding (Czech stuff) and Latin2/Win1250
on-the-fly recoding with 'set client_encoding' works smoothly. Now, when
I set client encoding to SQL_ASCII, accented characters are converted to
(hexa) codes. Is there any (simple) way to make this recoding convert
accented characters to just the chars themselves but without accents?
Thanks in advance.

P.S. Moreover, the non-Czech speakers tend to search the database with
words without accents, it would be usefull to make this conversion works
in the other direction: name LIKE 'ceske%' would return also names
starting with accented version.

P.S.2 I could do this quite easily in Perl on the application level, but
don't want to start programming before I'm sure there's no standard
postgres solution.
