ANSI/ISO encodings

Provides support for a variety of code pages. On Windows operating systems, code pages are used to support a specific language or group of languages. For a table that lists the code pages supported by the .NET Framework, see the Encoding class. You can retrieve an encoding object for a particular code page by calling the Encoding.GetEncoding(Int32) method.

A code page contains 256 code points and is zero-based. In most code pages, code points 0 through 127 represent the ASCII character set, and code points 128 through 255 differ significantly between code pages. For example, code page 1252 provides the characters for Latin writing systems, including English, German, and French. The last 128 code points in code page 1252 contain the accent characters. Code page 1253 provides character codes that are required in the Greek writing system. The last 128 code points in code page 1253 contain the Greek characters. As a result, an application that relies on ANSI code pages cannot store Greek and German in the same text stream unless it includes an identifier that indicates the referenced code page.
