PHP 7 utf8_encode() Function
Encode an ISO-8859-1 string to UTF-8:
$text = "\xE0";
Definition and Usage
The utf8_encode() function encodes an ISO-8859-1 string to UTF-8.
Unicode is a universal standard, and has been developed to describe all possible characters of all languages plus a lot of symbols with one unique number for each character/symbol.
However, it is not always possible to transfer a Unicode character to another computer reliably. UTF-8 has been developed to transfer a Unicode character from one computer to another.
