Well...I implemented it as a custom function but the problem is still there...
Same error:

SQLSTATE[22021]: Character not in repertoire: 7 ERROR: invalid byte
sequence for encoding "UTF8": 0xe3 0xa8 0x20


Any other suggestion?

You can create a custom DQL function [1] to implement ILIKE.

Hi all.
I'm working with Symfony 2.3, Doctrine 2.4 and PostgreSQL 9.2.
I just want to perform two simple queries, according to the value of a
checkbox. Such queries are:
1) SELECT * FROM table WHERE field LIKE 'Something'
2) SELECT * FROM table WHERE field ILIKE 'Something'
In PostgreSQL, the first is case sensitive, while the second is case
insensitive. I know that in Doctrine ILIKE does not exist and that I should
use the LOWER function. However, if I specify some special characters in
the query (for example 'รจ'), I get an error when I use the case insensitive
version (that is, when using the LOWER function).
In particular, the error I get is the following: SQLSTATE[22021]: Character not in repertoire: 7 ERROR: invalid byte
sequence for encoding "UTF8": 0xe3 0xa8 0x20
Everything works fine when I do not use the LOWER function. I already
checked the encoding and it is UTF8 for both the database and the
client_encoding parameter of PostgreSQL.
Any suggestion? Thank you
