CodePage簡介(轉)
從 Unicode 組織 取得GBK/Big5的Unicode的定義. 然后使用下面的程序就可以將其轉化為Linux核心需要的Unicode<->GBK碼表
./genmap BIG5.txt | perl uni2big5.pl
./genmap CP936.txt | perl uni2gbk.pl 再修改fat/vfat/ntfs的相關函數就可以完成對核心的修改工作. 具體使用時可以使用下面的命令: 簡體中文: mount -t vfat /dev/hda1 /mnt/1 -o codepage=936,iocharset=cp936 繁體中文: mount -t vfat /dev/hda1 /mnt/1 -o codepage=950,iocharset=cp936
cat $1 | awk '{if(index($1,"#")==0)print $0}' | awk 'BEGIN{FS="0x"}{print $2 $3}' |
awk '{if(length($1)==length($2))print $1,$2}'

1. Codepage的定義和歷史
字符內碼(charcter code)指的是用來代表字符的內碼.讀者在輸入和存儲文檔時都要使用內碼,內碼分為
- 單字節內碼 -- Single-Byte character sets (SBCS),可以支持256個字符編碼.
- 雙字節內碼 -- Double-Byte character sets)(DBCS),可以支持65000個字符編碼.主要用來對大字符集的東方文字進行編碼.
codepage 指的是一個經過挑選的以特定順序排列的字符內碼列表,對于早期的單字節內碼的語種,codepage中的內碼順序使得系統
可以按照此列表來根據鍵盤的輸入值給出一個對應的內碼.對于雙字節內碼,則給出的是MultiByte到Unicode的對應表,這樣就可以把
以Unicode形式存放的字符轉化為相應的字符內碼,或者反之,在Linux核心中對應的函數就是utf8_mbtowc和utf8_wctomb. ......1. Codepage的定義和歷史

在1980年前,仍然沒有任何國際標準如ISO-8859或Unicode來定義如何擴展US-ASCII編碼以便非英語國家的用戶使用.很多IT 廠商發明了他們自己的編碼,并且使用了難以記憶的數目來標識:
例如936代表簡體中文. 950代表繁體中文.
1.1 CJK Codepage
同 Extended Unix Coding ( EUC )編碼大不一樣的是,下面所有的遠東 codepage 都利用了C1控制碼 { =80..=9F } 做為首字節, 使用ASCII值 { =40..=7E { 做為第二字節,這樣才能包含多達數萬個雙字節字符,這表明在這種編碼之中小于3F的ASCII值不一定代表ASCII字符.
CP932
Shift-JIS包含日本語 charset JIS X 0201 (每個字符一個字節) 和 JIS X 0208 (每個字符兩個字節),所以 JIS X 0201平假名包含一個字節半寬的字符,其剩馀的60個字節被用做7076個漢字以及648個其他全寬字符的首字節.同EUC-JP編碼區別的是, Shift-JIS沒有包含JIS X 202中定義的5802個漢字.
CP936
GBK 擴展了 EUC-CN 編碼( GB 2312-80編碼,包含 6763 個漢字)到Unicode (GB13000.1-93)中定義的20902個漢字,中國大陸使用的是簡體中文zh_CN.
CP949
UnifiedHangul (UHC) 是韓文 EUC-KR 編碼(KS C 5601-1992 編碼,包括2350 韓文音節和 4888 個漢字a)的超集,包含 8822個附加的韓文音節( 在C1中 )
CP950
是代替EUC-TW (CNS 11643-1992)的 Big5 編碼(13072 繁體 zh_TW 中文字) 繁體中文,這些定義都在Ken Lunde的 CJK.INF中或者 Unicode 編碼表中找到.
注意: Microsoft采用以上四種Codepage,因此要訪問Microsoft的文件系統時必需采用上面的Codepage .
1.2 IBM的遠東語言Codepage
IBM的Codepage分為SBCS和DBCS兩種:
IBM SBCS Codepage
37 (英文) * 290 (日文) * 833 (韓文) * 836 (簡體中文) * 891 (韓文) 897 (日文) 903 (簡體中文) 904 (繁體中文)IBM DBCS Codepage
300 (日文) * 301 (日文) 834 (韓文) * 835 (繁體中文) * 837 (簡體中文) * 926 (韓文) 927 (繁體中文) 928 (簡體中文)將SBCS的Codepage和DBCS的Codepage混合起來就成為: IBM MBCS Codepage
930 (日文) (Codepage 300 加 290) * 932 (日文) (Codepage 301 加 897) 933 (韓文) (Codepage 834 加 833) * 934 (韓文) (Codepage 926 加 891) 938 (繁體中文) (Codepage 927 加 904) 936 (簡體中文) (Codepage 928 加 903) 5031 (簡體中文) (Codepage 837 加 836) * 5033 (繁體中文) (Codepage 835 加 37) **代表采用EBCDIC編碼格式
由此可見,Mircosoft的CJK Codepage來源于IBM的Codepage.
2. Linux下Codepage的作用
在Linux下引入對Codepage的支持主要是為了訪問FAT/VFAT/FAT32/NTFS/NCPFS等文件系統下的多語種文件名的問 題,目前在NTFS和FAT32/VFAT下的文件系統上都使用了Unicode,這就需要系統在讀取這些文件名時動態將其轉換為相應的語言編碼.因此引 入了NLS支持.其相應的程序文件在/usr/src/linux/fs/nls下:
- Config.in
- Makefile
- nls_base.c
- nls_cp437.c
- nls_cp737.c
- nls_cp775.c
- nls_cp850.c
- nls_cp852.c
- nls_cp855.c
- nls_cp857.c
- nls_cp860.c
- nls_cp861.c
- nls_cp862.c
- nls_cp863.c
- nls_cp864.c
- nls_cp865.c
- nls_cp866.c
- nls_cp869.c
- nls_cp874.c
- nls_cp936.c
- nls_cp950.c
- nls_iso8859-1.c
- nls_iso8859-15.c
- nls_iso8859-2.c
- nls_iso8859-3.c
- nls_iso8859-4.c
- nls_iso8859-5.c
- nls_iso8859-6.c
- nls_iso8859-7.c
- nls_iso8859-8.c
- nls_iso8859-9.c
- nls_koi8-r.c
實現了下列函數:
- extern int utf8_mbtowc(__u16 *, const __u8 *, int);
- extern int utf8_mbstowcs(__u16 *, const __u8 *, int);
- extern int utf8_wctomb(__u8 *, __u16, int);
- extern int utf8_wcstombs(__u8 *, const __u16 *, int);
這樣在加載相應的文件系統時就可以用下面的參數來設置Codepage:
對于Codepage 437 來說
mount -t vfat /dev/hda1 /mnt/1 -o codepage=437,iocharset=cp437
這樣在Linux下就可以正常訪問不同語種的長文件名了.
3. Linux下支持的Codepage
nls codepage 437 -- 美國/加拿大英語 nls codepage 737 -- 希臘語 nls codepage 775 -- 波羅的海語 nls codepage 850 -- 包括西歐語種(德語,西班牙語,意大利語)中的一些字符 nls codepage 852 -- Latin 2 包括中東歐語種(阿爾巴尼亞語,克羅地亞語,捷克語,英語,芬蘭語,匈牙利語,愛爾蘭語,德語,波蘭語,羅馬利亞語,塞爾維亞語,斯洛伐克語,斯洛文尼亞語,Sorbian語) nls codepage 855 -- 斯拉夫語 nls codepage 857 -- 土耳其語 nls codepage 860 -- 葡萄牙語 nls codepage 861 -- 冰島語 nls codepage 862 -- 希伯來語 nls codepage 863 -- 加拿大語 nls codepage 864 -- 阿拉伯語 nls codepage 865 -- 日爾曼語系 nls codepage 866 -- 斯拉夫語/俄語 nls codepage 869 -- 希臘語(2) nls codepage 874 -- 泰語 nls codepage 936 -- 簡體中文GBK nls codepage 950 -- 繁體中文Big5 nls iso8859-1 -- 西歐語系(阿爾巴尼亞語,西班牙加泰羅尼亞語,丹麥語,荷蘭語,英語,Faeroese語,芬蘭語,法語,德語,加里西亞語,愛爾蘭語,冰島語,意大利語,挪威語,葡萄牙語,瑞士語.)這同時適用于美國英語. nls iso8859-2 -- Latin 2 字符集,斯拉夫/中歐語系(捷克語,德語,匈牙利語,波蘭語,羅馬尼亞語,克羅地亞語,斯洛伐克語,斯洛文尼亞語) nls iso8859-3 -- Latin 3 字符集, (世界語,加里西亞語,馬耳他語,土耳其語) nls iso8859-4 -- Latin 4 字符集, (愛莎尼亞語,拉脫維亞語,立陶宛語),是Latin 6 字符集的前序標準 nls iso8859-5 -- 斯拉夫語系(保加利亞語,Byelorussian語,馬其頓語,俄語,塞爾維亞語,烏克蘭語) 一般推薦使用 KOI8-R codepage nls iso8859-6 -- 阿拉伯語. nls iso8859-7 -- 現代希臘語 nls iso8859-8 -- 希伯來語 nls iso8859-9 -- Latin 5 字符集, (去掉了 Latin 1中不經常使用的一些冰島語字符而代以土耳其語字符) nls iso8859-10 -- Latin 6 字符集, (因紐特(格陵蘭)語,薩摩斯島語等Latin 4 中沒有包括的北歐語種) nls iso8859-15 -- Latin 9 字符集, 是Latin 1字符集的更新版本,去掉一些不常用的字符,增加了對愛莎尼亞語的支持,修正了法語和芬蘭語部份,增加了歐元字符) nls koi8-r -- 俄語的缺省支持4. 簡體中文GBK/繁體中文Big5的Codepage
如何制作簡體中文GBK/繁體中文Big5的Codepage?
由于GBK是基于ISO 10646-1:1993標準的,而相應的日文是JIS X 0221-1995,韓文是KS C 5700-1995,他們被提交到Unicode標準的時間表為:
Unicode Version 1.0
Unicode Version 1.1 <-> ISO 10646-1:1993, JIS X 0221-1995, GB 13000.1-93
Unicode Version 2.0 <-> KS C 5700-1995
從Windows 95開始均采用GBK編碼. 您需要的是 CP936.TXT 和 BIG5.TXT
./genmap BIG5.txt | perl uni2big5.pl
./genmap CP936.txt | perl uni2gbk.pl
有趣的是,由于GBK包含了全部的GB2312/Big5/JIS的內碼,所以使用936的Codepage也可以顯示Big5的文件名.
