Unicode is a computer coding system that aims to unify text exchanges at the international level. With Unicode, each computer character is described by a name and a code (codepoint), identifying it uniquely regardless of the computer medium or the software used. Unicode has already listed over 100000 characters.

You can also fix some of these strings in PHP if necessary. Note that because characters have been encoded twice

Unicode encryption can be made by displaying the Unicode codes of each of the characters in the message.
