翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク character encoding ： FOLDOC character encoding (Or "character encoding scheme") A mapping of binary values to code positions and back; generally a 1:1 (bijective) mapping. In the case of ASCII, this is generally a f(x)=x mapping: code point 65 maps to the byte value 65, and vice versa. This is possible because ASCII uses only code positions representable as single bytes, i.e., values between 0 and 255, at most. (US-ASCII only uses values 0 to 127, in fact.) Unicode and many CJK coded character sets use many more than 255 positions, requiring more complex mappings: sometimes the characters are mapped onto pairs of bytes (see DBCS). In many cases, this breaks programs that assume a one-to-one mapping of bytes to characters, and so, for example, treat any occurrance of the byte value 13 as a carriage return. To avoid this problem, character encodings such as UTF-8 were devised. (1998-10-18) スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016. All Rights Reserved.
