UnicodeDecodeError：コーデック位置105でバイト0xe2をデコードすることはできません「UTF-8」が：無効な継続バイト

私のコードはかなり次のようである：UnicodeDecodeError：コーデック位置105でバイト0xe2をデコードすることはできません「UTF-8」が：無効な継続バイト

import sqlitefts as fts 

connection = apsw.Connection('texts.db', flags=apsw.SQLITE_OPEN_READWRITE) 
c = connection.cursor() 
def do_search(query): 
    c.execute('SELECT title, book, author, link, snippet(text_idx) FROM text_idx WHERE text_idx MATCH 'possumus';') #in this case query='possumus' 
    c.fetchall() 
--display the results on html--

私は、単一以上を検索する場合、クエリが動作しますワード。しかし、私は単一の単語の検索を行うと、それは私にデコードエラーを投げる。動作しません

クエリは、次のようにしている：のような

単一ワード検索 -

SELECT title, book, author, link, snippet(text_idx) 
FROM text_idx 
WHERE text_idx MATCH 'possumus';

とORスタックトレースがある

SELECT title, book, author, link, snippet(text_idx) 
FROM text_idx 
WHERE text_idx MATCH 'quam OR Galliae';

のように検索します。

私のクエリでsnippet()関数を使用しないと、クエリは正常に動作します。
