Originally based on the (modern) English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart in this article. [12] Ninety-five of the encoded characters are printable: these include the digits 0 to 9, lowercase letters a to z, uppercase letters A to Z, and punctuation symbols.
Only the symbols in the latest IPA chart are included. The numbers in the leftmost column, according to which the symbols are sorted, are the IPA Numbers.Some of the IPA symbols to which a system lacks a corresponding symbol may still be represented in that system by use of a modifier (diacritic), but such combinations are not included unless the documentation explicitly assigns one for the value.
The block contains all the letters and control codes of the ASCII encoding. It ranges from U+0000 to U+007F, contains 128 characters and includes the C0 controls, ASCII punctuation and symbols, ASCII digits, both the uppercase and lowercase of the English alphabet and a control character.
ASCII's English alphabet almost accommodates European languages, if accented letters are replaced by non-accented letters or two-character approximations such as ss for ß. Modified variants of 7-bit ASCII appeared promptly, trading some lesser-used symbols for highly desired symbols or letters, such as replacing "#" with "£" on UK Teletypes ...
Punched tape with the word "Wikipedia" encoded in ASCII.Presence and absence of a hole represents 1 and 0, respectively; for example, W is encoded as 1010111.. Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers.

In the ASCII standard, the numbers 0-31 and 127 are assigned to control characters, for instance, code point 7 is typed by Ctrl+G. While some (most?) applications would insert a bullet character • (code point 7 on code page 437 ), some would treat this identical to Ctrl + G which often was a command for the program.
This is simply the ASCII character codes from 32 to 95 coded as 0 to 63 by subtracting 32 (i.e., columns 2, 3, 4, and 5 of the ASCII table (16 characters to a column), shifted to columns 0 through 3, by subtracting 2 from the high bits); it includes the space, punctuation characters, numbers, and capital letters, but no control characters.
If Braille ASCII is viewed in a word processor, it will look like a jumbled mix of letters, numbers, and punctuation. However, there are several fonts available, many of them free, which allow the user to view and print Braille ASCII as simulated braille, i.e. a graphical representation of braille characters.
