将字符转换成PDF [英] escaping characters for substitution into a PDF

问题描述

任何人都可以告诉我一组PDF文件的控制字符，以及如何解除它们？我有一个（非放气的（膨胀的））PDF文件，我想编辑文本，但我害怕用括号和东西意外地做一些控制序列。

Can anyone tell me the set of control characters for a PDF file, and how to escape them? I have a (non-deflated (inflated?)) PDF document that I would like to edit the text in, but I'm afraid of accidentally making some control sequence using parentheses and stuff.

谢谢。

推荐答案

好吧，我想我找到了。在 PDF 1.7规格（PDF链接）的第15页，似乎只有字符我需要担心的是括号和反斜杠。

Okay, I think I found it. On page 15 of the PDF 1.7 spec (PDF link), it appears that the only characters I need to worry about are the parentheses and the backslash.

Sequence | Meaning
---------------------------------------------
\n       | LINE FEED (0Ah) (LF)
\r       | CARRIAGE RETURN (0Dh) (CR) 
\t       | HORIZONTAL TAB (09h) (HT)
\b       | BACKSPACE (08h) (BS)
\f       | FORM FEED (FF)
\(       | LEFT PARENTHESIS (28h)
\)       | RIGHT PARENTHESIS (29h)
\\       | REVERSE SOLIDUS (5Ch) (Backslash)
\ddd     | Character code ddd (octal)
