Hi @gardbeat,
Related: Incidencia idioma caracteres especiales
The likeliest cause is that something changed with your database, e.g. it was dumped and reloaded inconsistently (changing the database set unintentionally). Alternately, check your config.inc.php to make sure that the character set configuration didn’t change there accidentally.
