What is unicode

Question

Someone make a code alert with text example:Hello world. without using any word... they use symbols... someone call that unicode... what is that?

Answer 1

In earlier date of computing there was ASCII standard characters set, but it is limited to latin character sets, and only 256 characters, many other nations using non latin characters were left unsupported.

Then computer scientists came up with Unicode, a standard that defines multi-byte characters which gives better support for non latin characters, a single Unicode character can consists from 1 up to 4 bytes.
