9 //********************hyperref书签文件编码规则**************************
10 //每个书签以如下形式存放 :\BOOKMARK [1][-]{section.0.1}{书签正文}{}
11 //非unicode模式下使用hyperref宏包，bookmark中的部分特殊字符以\ooo的形式插入
12 //' ':\040, '#':\043, '$':\044, '%':\045, '&':\046, '\':\134, '^':\136, '_':\137, '{':\173, '}':\175, '~':176
13 //比较特殊的是'('和')'，是以'\('和'\)'的形式插入的，而不是\ooo形式
14 //\S:\247
15 //所有其他字符和汉字均不作任何处理，在bookmark中保留
16 //已经知道，这种保留会造成部分汉字在bookmark中无法显示
17 //当使用\CJKchar{"0081}{"040}方式直接以GBK代码的方法插入汉字，bookmark中会生成如下的书签代码：
18 //"0081"040，显然，pdflatex忽略了\CJKchar命令本身和前后的{}把参数当做普通文本做了转换
19 //'^^xx^^yy'形式的CJK汉字在.out中有两种可能的出现方式：'^^xx^^yy'和'^^xxL'
20 /////////////////////////////////////////////////////////////////////////////////////////////////////////////
21 //unicode模式下使用hyperref宏包，bookmark特殊字符均编码为\ooo\ooo或者\000x或者\000x\80y形式的unicode代码
22 zlb 1.1 //书签内容均以\376\377开头作为前导标示符
23 //经过实验，相应的bookmarkunicode代码插入规则如下：
24 //*****A类：编码为\ooo\ooo的特殊字符部分*****
25 //' '(空格):\000\040，使用\textvisiblespace也得到同样的书签
26 //'#'(\#):\000\043, '$'(\$):\000\044, '%'(\%):\000\045, '&'(\&):\000\046
27 //'(':\000\050; ')':\000\051
28 //'\'(\textbackslash):\000\134;
29 //'^'(\textasciicircum):\000\136; '_'(\_):\000\137
30 //'{'(\{):\000\173; '}'(\}):\000\175
31 //'~'(\textasciitilde):\000\176;
32 //*****B类：编码为\000x的普通字符部分，其中x表示字符本身*****
33 //abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789
34 //|:',./!?;"-+=[]`*@(直接用@即可，无需\@)<(或\textless)>(或\textgreater)
35 //*****C类：单个汉字*****
36 //假设其高位码为H，低位码为L，则一般的GB汉字其插入形式为：\000H\80L
37 //但是上述情况存在例外，当L为普通拉丁字符时，将会以\000HL的形式插入
38 //如果任何汉字出现在一个低位为拉丁字符的GBK汉字之后，第二个汉字会以\80H\000L的形式出现
39 //只有\80HL是不可能出现的汉字代码
40 //当书签中包含多个汉字的时候，重复按照上述规则插入，汉字中间的其他字符按照正常规则插入
41 /////////////////////////////////////////////////////////////////////////////////////////////////////////////
42 //@注意：当汉字低位字节为字符'}{~\_^'时，tex文档编译会出现错误，强行编译可能出现不可预测的行为
43 zlb 1.1 //@插入out文件的内容变得很混乱，一般书签正文会在低位'}'出现之后终止，gbk2uni只尽可能地消除这种影响
44 //@这可能使得部分GBK汉字在书签中消失或者显示为其他字符
45 //@使用张林波老师随CCT新版发行的cctconv程序可以解决这个问题
46 //@cctconv把汉字低位字节为'\', '{', '}', '^', '_', '~'的汉字低位字节分别改为'012345'以方便处理
47 //@或者使用-f开关转换可以将所有高位为1的字符转换为^^xx的形式，这在一些老的不支持扩展字符的tex系统中有用
48 //@gbk2uni处理这样的汉字假设cctconv已经运行（cctconv与CJK兼容，无需cct.sty即可得到正确的dvi文件）
49 //@这样的汉字经cctconv处理后，插入out文件的对应内容在unicode模式下有两种可能：
50 //@sprintf("\\000%d\\%03o", H, L)和sprintf("%d\\%03o", H, L)，这里L已经是被转换回来的'}{~\_^'
51 //现在还不清楚是否也有sprintf("\\80%d\\%03o", H, L)形式出现（根据'\80HL'不出现推测这种形式可能也不出现）
52 /////////////////////////////////////////////////////////////////////////////////////////////////////////////
53 //*****D类：\CJKchar{"00ab}{"0cd}形式的CJK汉字*****
54 //\000"\0000\0000\000a\000b\000"\0000\000c\000d
55 //显然，unicode模式的hyperref是如下工作的：
56 //第一步先生成非unicode模式的out文件，接着对其中的扩展字符做了一个后处理，但是这个处理对汉字不正确
57 //*****E类：'^^xx^^yy'形式的CJK汉字*****
58 //在unicode模式下，.out文件的内容一般为'\000^^xx\80^^yy'或者'\000^^xx\80L'
59 //估计其他CJK汉字的样式也可能出现：'\80^^xx\000^^yy'、'\80^^xx\000L'、'\000^^xx^^yy'、'\000^^xx\ooo'
60 //以上情况说明，在处理过程中，我们可以像TeX那样将每一个'^^xx'码字当成普通的ASCII字符来处理即可兼容'^^xx'代码
61 /////////////////////////////////////////////////////////////////////////////////////////////////////////////
62 //如果\CJKchar{}{}中的前后两个参数位数不同，单从.out文件无法判断第二个参数何时结束
63 //因此，gbk2uni要求在tex文档中统一采用三位十六进制法\CJKchar{"0xx"}{"0xx}表示前后两个参数
64 zlb 1.1 //考虑到在实际中\CJKchar用的比较少，这个约定应该不会算大的限制。
