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

If you see those characters you probably just didn’t specify the character encoding properly. Because those characters are the result when an UTF-8 multi-byte string is interpreted with a single-byte encoding like ISO 8859-1 or Windows-1252.

In this case ë could be encoded with 0xC3 0xAB that represents the Unicode character ë (U+00EB) in UTF-8.
