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.
A character encoding is a system that pairs each character in a supported character set with some value that represents that character.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 Unicode Transformation Format (UTF) encodings define ways to encode that code point into a sequence of one or more bytes. Each instance represents a buffer that contains the fallback characters that will replace the character that cannot be encoded or the byte sequence that cannot be decoded. A Unicode encoding scheme simplifies world-ready application development because it allows characters from any character set to be represented in a single encoding. When you create a custom fallback solution for an encoder or decoder, you must implement the following members: If the fallback implementation is a best-fit fallback or a replacement fallback, the classes derived from Encoder Fallback Buffer and Decoder Fallback Buffer also maintain two private instance fields: the exact number of characters in the buffer; and the index of the next character in the buffer to return. NET, do the following: Note The Unicode Standard assigns a code point (a number) and a name to each character in every supported script. Create Fallback Buffer method is called by the decoder when it encounters one or more bytes that it is not able to decode.
For example, the character "A" is represented by the code point U 0041 and the name "LATIN CAPITAL LETTER A". The Encoder Fallback Buffer and Decoder Fallback Buffer classes provide the fallback implementation.
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.
Application developers no longer have to keep track of the encoding scheme that was used to produce characters for a specific language or writing system, and data can be shared among systems internationally without being corrupted. NET supports three encodings defined by the Unicode standard: UTF-8, UTF-16, and UTF-32. Write Line("Unable to encode 0x at index .", Convert. An earlier example used replacement fallback to replace Unicode characters that did not correspond to ASCII characters with an asterisk (*).
For more information, see The Unicode Standard at the Unicode home page. The following example uses a custom best-fit fallback implementation instead to provide a better mapping of non-ASCII characters.
Depending on the encoding used, converting binary data to string format with the encoding classes can introduce unexpected behavior and produce inaccurate or corrupted data. NET uses the UTF-16 encoding (represented by the Unicode Encoding class) to represent characters and strings. Instances of these classes are passed to the Encoding.
