I wonder if the OP is doing something like this:

test=> SELECT getdatabaseencoding();
 getdatabaseencoding 
---------------------
 LATIN2
(1 row)

test=> SHOW client_encoding;
 client_encoding 
-----------------
 win1250
(1 row)

test=> CREATE TABLE test (t text);
CREATE TABLE
test=> INSERT INTO test VALUES (E'\202\232'); -- \202=0x82, \232=0x9a
INSERT 0 1
test=> SELECT * FROM test;
ERROR:  character 0x829a of encoding "MULE_INTERNAL" has no equivalent in "WIN1250"

The intent might be that E'\202\232' is a string in the client's
encoding, where it would represent the same characters as Unicode
<U+201A SINGLE LOW-9 QUOTATION MARK, U+0161 LATIN SMALL LETTER S
WITH CARON> (I'm using Unicode as the pivot for convenience).  But
the backend is handling the string in the database's encoding, where
it represents <U+0082,U+009A>, which are control characters that
don't have mappings in win1250; hence the conversion error when the
client tries to read the data.

Just a guess.
