[Cdrdao-devel] String escaping in TOC files

[Andreas R. <and...@gm...>]

Dear all,

while testing Ardour's (www.ardour.org) TOC file generation
routines, I found that while cdrdao uses the backslash in TOC files
for escaping double quotes and allowing for octal notation of
characters it *does not* allow the backslash itself to be escaped.

To avoid any trouble a program generating a toc file will have to
write a normal backslash in octal notation. Which is fine, but
probably should be documented.

No what I have trouble with is that cdrdao does not do that itself
when writing a toc file while reading a CD.

Example:
Use any toc/wav image with CD text you have around, change the CD
title to:

    TITLE "MyTestDisc\134"

The \134 will be correctly interpreted as backslash and written as
such onto your CD. Now when you rip the same CD with cdrdao, the
resulting toc has:

    TITLE "MyTestDisc\"

which, when fed to cdrdao will break the toc parser.

Is there any specific reason of this behaviour? Are any programs
using cdrdao relying on this behaviour? And if not, what's the best
place to upload a patch?

Best regards

Andreas
