integrated tsearch doesn't work with non utf8 database

Hello

last time I checked utf8 database. Now I checked latin2 encoding
database. I used dictionaries from last test.

client_encoding | utf8
lc_collate | cs_CZ.iso-8859-2
lc_ctype | cs_CZ.iso-8859-2
lc_messages | cs_CZ.iso-8859-2
lc_monetary | cs_CZ.iso-8859-2
lc_numeric | cs_CZ.iso-8859-2
lc_time | cs_CZ.iso-8859-2

postgres=# create Text search dictionary cspell2(template=ispell,
afffile=czech, dictfile=czech);
CREATE TEXT SEARCH DICTIONARY
postgres=# alter text search configuration cs alter mapping for word,
lword with cspell2, simple;
ALTER TEXT SEARCH CONFIGURATION
postgres=# select ts_debug('cs','Příliš žluťoučký kůň se napil žluté vody');
ERROR: character 0xc3a5 of encoding "UTF8" has no equivalent in "LATIN2"
CONTEXT: SQL function "ts_debug" statement 1
postgres=#

database was initialised

/usr/local/pgsql/bin/initdb --encoding=latin2
--locale=cs_CZ.iso-8859-2 -D /usr/local/pgsql/data/

locales is correct

postgres=# set client_encoding to utf8;
SET
postgres=# select upper('Příliš žluťoučký kůň se napil žluté vody');
upper
------------------------------------------
PŘÍLIŠ ŽLUŤOUČKÝ KŮŇ SE NAPIL ŽLUTÉ VODY
(1 row)
