Frequently Asked Questions About Text to ASCII Converter
What is ASCII?
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns a unique number to each character. For example, uppercase "A" is 65, lowercase "a" is 97, and the digit "0" is 48. ASCII covers 128 characters including letters, digits, punctuation, and control codes.
What is the ASCII code for common characters?
Space = 32, digits 0-9 = 48-57, uppercase A-Z = 65-90, lowercase a-z = 97-122. Punctuation marks have various codes between 33 and 126.
Does this support Unicode/emoji?
Characters beyond ASCII (128+) are shown as their Unicode code point values since they are not part of the standard ASCII table. This includes accented letters, special symbols, and emoji.
