> QueryUtil converts the query statement to a UTF-8 encoded byte array which is used as input to the lexer instead of using the string directly. 
> Instead of
>     CharStream input = new ANTLRInputStream(new ByteArrayInputStream(statement.getBytes("UTF-8")));
> the input stream should be obtained like this:
>     CharStream input = new ANTLRStringStream(statement);
> The former method transforms the characters in the contains clause of the query 
>     SELECT * FROM cmis:document WHERE CONTAINS ('\u4E2D\u6587')
> in an incorrect way.
