![ç 在 \write 和 \read 中不起作用](https://linux22.com/image/323112/%C3%A7%20%E5%9C%A8%20%5Cwrite%20%E5%92%8C%20%5Cread%20%E4%B8%AD%E4%B8%8D%E8%B5%B7%E4%BD%9C%E7%94%A8.png)
在 Plain TeX 中,当我在字符串中执行\write
包含ç
或Ç
时,它会被扩展,从而在输出文件中生成大量代码,这些代码无法读回。我在阅读目录时遇到了这个问题:

我尝试重新定义\c c
(这会使 Plain Tex 中的 ç)\def\c #1 {\accent 24 #1}
并且效果很好,但它在\c C
(Ç)中未对齐并且与字体无关,我已经尝试了很多。
我搞不懂。有什么想法吗?
答案1
由于您正在使用pdftex
,因此您可以做得更好,而不是\c
在章节标题中的每个(或其他重音)前面加上前缀\noexpand
。
我们要\protected
在重音宏的定义前面添加。由于它\c
接受一个参数,因此你可以通过以下方式执行此操作
\begingroup
\toks0=\expandafter{\c{#1}}
\edef\x{\endgroup
\protected\def\noexpand\c##1{\the\toks0}}\x
现在只需抽象这个定义即可:
\def\protectaccent#1{%
\begingroup
\toks0=\expandafter{#1{##1}}%
\edef\x{\endgroup
\protected\def\noexpand#1####1{\the\toks0}}\x
}
\protectaccent\c
\protectaccent\'
\protectaccent\^
(添加您需要的重音符号)。此后,\c
章节标题将直接显示在.toc
文件上。
完整示例
\def\protectaccent#1{%
\begingroup
\toks0=\expandafter{#1{##1}}%
\edef\x{\endgroup
\protected\def\noexpand#1####1{\the\toks0}}\x
}
\protectaccent\c
\protectaccent\'
\protectaccent\^
\immediate\write20{\c c\'a}
{\tt\meaning\'}
\c c\'a\^o

答案2
\noexpand
在这种情况下您可以使用:
\write1 {\noexpand\c c is now OK :-)}
答案3
您可以使用 csplain。例如命令pdfcsplain
。输入:
\input utf8lat1
\immediate\write16{====== normal text: çáô}
text: çáô
\end
