Text Search Configuration Problem

I'm using Postgresql version 8.3.1 on CentOS 5 and am following the steps in section 12.7 of the documentation for creating a custom text search configuration.

 

When I get to the step that says:

 

CREATE TEXT SEARCH DICTIONARY english_ispell (
    TEMPLATE = ispell,
    DictFile = english,
    AffFile = english,
    StopWords = english
);

 

I get the following error:

 

ERROR:  invalid byte sequence for encoding "UTF8": 0xe0c020
HINT:  This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding".

 

I'm using the english ispell files from http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/

 

Does anyone know how to solve this?
