ASCII, which stands for "American Standard Code for Information Interchange," is a character encoding standard that was developed in the early 1960s to represent text and control characters in computers and communication equipment.
It's one of the foundational building blocks of modern computing and is still widely used today, though it has been largely supplemented by more advanced character encoding standards like UTF-8.

Limitations of ASCII
ASCII is limited to representing a relatively small set of characters. It primarily includes the characters used in the English language, such as letters (both uppercase and lowercase), numbers, punctuation marks, and some control characters.
Therefore:
It does not support characters from other languages or writing systems.
It doesn't have support for emojis or other special characters.
