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
