French Characters

I created a database using UNICODE Characterset.

Created a table
CREATE TABLE a (
a char(30)
);

Tried to insert a row through PG_ADMIN
insert into a values('qualité')

This resulted in the following error

Number: -2147467259
Description: ERORR: Invalid UNICODE character sequence found (0xe90000)

I believe It's because of the French character "é" .

We need to insert French characters in the database.

The DATABASE is UNICODE
Is there anything which I am missing.

Please Advice
