ASCII was the first character encoding standard for the web. It defined 128 different characters that could be used on the internet:

English letters (A-Z)
Numbers (0-9)
Special characters like ! $ + - ( ) @ < >.

The ANSI Character Set

ANSI (Windows-1252) was the original Windows character set:

Identical to ASCII for the first 127 characters
Special characters from 128 to 159
Identical to UTF-8 from 160 to 255
