There is no formal definition of "extended ASCII", and even use of the term is sometimes criticized, [1] [2] [3] because it can be mistakenly interpreted to mean that the American National ...
Windows-1252 or CP-1252 ( Windows code page 1252) is a legacy single-byte character encoding [2] that is used by default in Microsoft Windows throughout the Americas, Western Europe, Oceania, and much of Africa . Initially the same as ISO 8859-1, it began to diverge starting in Windows 2.0 by adding additional characters in the 0x80 to 0x9F ...

Table rows 8 to 10, codes 128 to 175 (80 hex to AF hex), are a selection of international text characters. Table rows 11 to 13, codes 176 to 223 (B0 hex to DF hex), are box drawing ...
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
ISO-8859-1 was (according to the standard, at least) the default encoding of documents delivered via HTTP with a MIME type beginning with text/. As of April 2024, 1.2% of all (and 15 of the top 1000 [1]) web sites use ISO/IEC 8859-1. [2] [3] It is the most declared single-byte character encoding, but as Web browsers and the HTML5 standard [4 ...
In version 13.0, Unicode was extended with another block containing many graphics characters, Symbols for Legacy Computing, which includes a few box-drawing characters and other symbols used by obsolete operating systems (mostly from the 1980s). Few fonts support these characters, but the table of symbols is provided here:
A code point, codepoint or code position is a particular position in a table, where the position has been assigned a meaning. The table may be one dimensional (a column), two dimensional (like cells in a spreadsheet), three dimensional (sheets in a workbook), etc... in any number of dimensions. Technically, a code point is a unique position in ...
