代碼(code)是程序員用開發(fā)工具所支持的語言寫出來的源文件,是一組由字符、符號或信號碼元以離散形式表示信息的明確的規(guī)則體系。
對于字符和Unicode數(shù)據(jù)的位模式的定義,此模式代表特定字母、數(shù)字或符號(例如 0x20 代表一個空格,而 0x74 代表字符“t”)。一些數(shù)據(jù)類型每個字符使用一個字節(jié);每個字節(jié)可以具有 256 個不同的位模式中的一個模式。
在計算機(jī)中,字符由不同的位模式(ON 或 OFF)表示。每個字節(jié)有 8 位,這 8 位可以有 256 種不同的 ON 和 OFF 組合模式。對于使用 1 個字節(jié)存儲每個字符的程序,通過給每個位模式指派字符可表示最多 256 個不同的字符。2 個字節(jié)有 16 位,這 16 位可以有 65,536 種唯一的 ON 和 OFF 組合模式。使用 2 個字節(jié)表示每個字符的程序可表示最多 65,536 個字符。
單字節(jié)代碼頁是字符定義,這些字符映射到每個字節(jié)可能有的 256 種位模式中的每一種。代碼頁定義大小寫字符、數(shù)字、符號以及 !、@、#、% 等特殊字符的位模式。每種歐洲語言(如德語和西班牙語)都有各自的單字節(jié)代碼頁。
雖然用于表示 A 到 Z 拉丁字母表字符的位模式在所有的代碼頁中都相同,但用于表示重音字符(如"é"和"á")的位模式在不同的代碼頁中卻不同。如果在運(yùn)行不同代碼頁的計算機(jī)間交換數(shù)據(jù),必須將所有字符數(shù)據(jù)由發(fā)送計算機(jī)的代碼頁轉(zhuǎn)換為接收計算機(jī)的代碼頁。如果源數(shù)據(jù)中的擴(kuò)展字符在接收計算機(jī)的代碼頁中未定義,那么數(shù)據(jù)將丟失。
如果某個數(shù)據(jù)庫為來自許多不同國家的客戶端提供服務(wù),則很難為該數(shù)據(jù)庫選擇這樣一種代碼頁,使其包括所有客戶端計算機(jī)所需的全部擴(kuò)展字符。而且,在代碼頁間不停地轉(zhuǎn)換需要花費(fèi)大量的處理時間。
