Import Language XML File error

[jasbell]

When I went to import a Portuguese language xml file I entered "Portugu?se" in the field named "Title for Uploaded Language" and got the below database error. This concerns me because I know that I configured MySQLI OPTIONS in the config.php with the line:
$config['Mysqli']['charset'] = 'utf8';

Below is the error, and I just want to know what this means, and why I could not insert a UTF-8 compliant word.


Database error in vBulletin 3.6.4:

Invalid SQL:
SELECT languageid FROM language WHERE title = 'Portugu?se';

MySQL Error : Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='
