ASCII has 256 this is able to be the case in prolonged. Initially its character codes have been 7 bits lengthy, however then it was prolonged to have a bit size of 8. Authentic = 128 characters, prolonged = 256. If not, then utilizing Unicode to extend storage dimension.

Unicode represents most written languages on the planet. ASCII has its equal in Unicode. The distinction between ASCII and Unicode is that ASCII represents lowercase letters (a-z), uppercase letters (A-Z), digits (0–9) and symbols equivalent to punctuation marks whereas Unicode represents letters of English, Arabic, Greek and so on. mathematical symbols, historic scripts, emoji overlaying a variety of characters than ASCII.
