About ASCII and Extended ASCII

ASCII (American Standard Code for Information Interchange) is a character encoding standard originally published in 1963. It defines 128 character codes (0–127) including control characters (0–31 and 127) and printable characters (32–126) such as letters, digits and punctuation. ASCII became the foundation for text representation in computers and telecommunications.

Extended ASCII is a loosely defined term that refers to the additional 128 codes (128–255) available when using 8-bit bytes. There are multiple extended sets (for example ISO-8859-1 / Latin-1, Windows-1252) that assign different characters to these codes. This page shows the extended range interpreted as Latin-1 / common Windows-1252 glyphs in modern browsers. Because extended ASCII depends on the code page, specific descriptions or glyphs can vary between systems.

Usage tips

Use the HTML numeric reference (e.g. &#`...`) shown in the table to embed characters reliably in HTML.
Remember that control characters are non-printable and are used for control purposes (newlines, tabs, escape sequences).
For consistent cross-platform text, prefer Unicode (UTF-8) which includes the full ASCII range and a much larger set of characters.
