Windows-1252, sometimes incorrectly called "ANSI". Blue dots indicate unused or control characters

Windows-1252 or CP-1252 is a character encoding of the Latin alphabet, used by default in the legacy components of Microsoft Windows in English and some other Western languages. It is one version within the group of Windows code pages.

Details[edit]

This character encoding is a superset of ISO 8859-1, but differs from the IANA's ISO-8859-1 by using displayable characters rather than control characters in the 80 to 9F (hex) range. Notable additional characters are curly quotation marks, the Euro sign, and all the printable characters that are in ISO 8859-15. It is known to Windows by the code page number 1252, and by the IANA-approved name "Windows‑1252".

It is very common to mislabel Windows-1252 text with the charset label ISO-8859-1. A common result was that all the quotes and apostrophes (produced by "smart quotes" in word-processing software) were replaced with question marks or boxes on non-Windows operating systems, making text difficult to read. Most modern web browsers and e-mail clients treat the MIME charset ISO-8859-1 as Windows-1252 to accommodate such mislabeling. This is now standard behavior in the draft HTML 5 specification, which requires that documents advertised as ISO-8859-1 actually be parsed with the Windows-1252 encoding.[1]

Historically, the phrase "ANSI Code Page" (ACP) is used in Windows to refer to various code pages considered as native. The intention was that most of these would be ANSI standards such as ISO-8859-1. Even though Windows-1252 was the first and by far most popular code page named so in Microsoft Windows parlance, the code page has never been an ANSI standard. Microsoft-affiliated bloggers now state that "The term ANSI as used to signify Windows code pages is a historical reference, but is nowadays a misnomer that continues to persist in the Windows community."[2]

In LaTeX packages, CP-1252 is referred to as "ansinew".

Code page layout[edit]

The following table shows Windows-1252. Each character is shown with its Unicode equivalent and its decimal code. Conversions to Unicode are based on the Unicode.org mapping of Windows-1252 with "best fit".[3]

Legend: yellow cells are control characters, blue cells are punctuation, purple cells are numbers, green cells are ASCII letters, and tan cells are international letters. Differences from ISO-8859-1 are marked with thick green borders.

According to the information on Microsoft's and the Unicode Consortium's websites, positions 81, 8D, 8F, 90, and 9D are unused; however, the Windows API MultiByteToWideChar maps these to the corresponding C1 control codes.

The euro character at position 80 was not present in earlier versions of this code page, nor were the S, s, Z, and z with caron (háček).
