How to search for any quoted-insert ctrl character

How to search for any quoted-insert ctrl character

[Deric Bytes]

I want to do a re-search-forward for any ^ charcter, even if it is a quoted-insert symbol


The following expression will not see text that has been entered using 'quoted-insert'


   (re-search-forward "^")

I want it to match the following three quoted-insert characters (and all others)

^R
^T
^P

Whey you type C-q C-r you don't get ^ character but the Control+R
character (Unicode U+0012). It's just displayed as ^R. When you want to
search for those characters you need to put them literally in your
regexp string:

    (re-search-forward "[^R^T^P^]")

Use C-q C-r, C-q C-t and C-q C-p to insert them.

Thanks @Teemu

I have found a hack. The quoted-inserts I am searching for are inside quotes.
so I can use a character class

(re-search-forward "\"[[:cntrl:]]\"")
