POST input is empty if contains accented characters.

Hi there folks.

I'm trying to debug a CI app to a friend of mine. The issue is that $this->input->post('name'); is empty if a accented character is sent.
Eg.:

If I send the name as Testing, then the value of $this->input->post('name'); is also Testing.
But if I send the name as Accentuátion (or anything with special accent characters), the the value of $this->input->post('name'); is "" (empty).

Any clue of what might be causing this issue of how to fix it?


Thanks!
