php - How to convert these strange characters? (ë, Ã, ì, ù, Ã)

Question

My page often shows things like ??, ?, ??, ?1, ? in place of normal characters.

I use utf8 for header page and MySQL encode. How does this happen?

Answer 1

These are utf-8 encoded characters. Use utf8_decode() to convert them to normal ISO-8859-1 characters.
