ASCII : Java Glossary

ASCII

The term ASCII has different meanings depending on context. Strictly speaking, ASCII (American Standard for Information Interchange) is a code that assigns the letters of the alphabet, digits and punctuation to the numbers 0 to 127. ASCII has no accented letters because it is designed for US-English only.

If I said, "That word processing file is vanilla ASCII", it means it contains no formatting characters — just the control characters, letters A to Z, digits 0 to 9 and punctuation
If I said "That file is ASCII not EBCDIC", it means your file encodes the letter A as the number 65, B as 66 etc., rather than some other method.
If I said "That file is pure ASCII, no high bit characters" it means the file contains just the ordinary characters — no accented letters or line drawing set.
If I said "I’m going to send this to you in raw ASCII protocol" it means I will be just sending you the raw characters, with nothing extra to help detect or correct errors — just the raw keystrokes.
You might wonder why '0' is not assigned binary code 0. Back in the days of paper tape, blank tape was binary code 0, which was sloughed over. So 0 had to be assigned the null control code. Further you could erase tape by punching out all the holes, so binary 1111111 had to be assigned the control code del.

ASCII has been expanded in many different ways with codes 128 to 255. The most common is called Latin-1. A number of new entities have been added since I wrote the list part of the HTML Cheat Sheet.

ASCII and Latin-1 Character Table

The letters of the alphabet, the digits 0 to 9, the punctuation, and the control characters are assigned numbers 0 to 127. This standard assignment is called ASCII. It is has been expanded in many different ways with codes 128 to 255. The most common is called Latin-1. See encoding for a list of various other possible encodings. This table shows you how the 255 possible 8-bit characters are rendered. It will look different depending on which encoding and font you are using in your browser. If your browser is configured properly this table will display the Latin-1 characters. If you want to see the HTML codes that will always render the same way no matter what your browser encoding, (encoding-agnostic) see this HTML table.

^A means control-A, the code you generate by holding down the Ctrl key and tapping A.

If the left hand column does not render properly, it means your browser is ignoring the Latin-1 charset command

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

or you don’t have a font installed that can display the Latin-1 characters.
