I hope I'm not completely missing the point here.
It seems there is a lot of searching for characters that need to be escaped, and changing the SD because of file content.
In that case, it might save some work to decide what you want to use for the SD, say '|', and include it in a group of others you want to escape, such as $,/". etc.
Sed has a character '&' which stands for "what was found". You could use it something like this and do all your escaping in one go, and not have to change the SD so much:
Code:
sed 's|["$/\|\@]|\\&|g'
Am I even close to what you need?

CSS::DOM::Util(3pm) User Contributed Perl Documentation CSS::DOM::Util(3pm)NAME
CSS::DOM::Util - Utility functions for dealing with CSS tokens
VERSION
Version 0.14
SYNOPSIS
use CSS::DOM::Util ':all';
# or:
use CSS::DOM::Util qw[
escape unescape
escape_ident unescape_url
escape_str unescape_str
];
DESCRIPTION
This module provides utility functions for dealing with CSS tokens.
FUNCTIONS
All functions below that take one argument have a "($)" prototype, so they have the same precedence as "closedir" and "delete".
escape $string, $chars_to_escape
This escapes any characters in $string that occur in $chars_to_escape, which is interpreted as a regular expression. The regexp must
consume just one character; otherwise you'll find chars missing from the output. ASCII vertical whitespace (except the vertical tab) is
always escaped.
Printable non-alphanumeric ASCII characters and the space character are escaped with a single backslash. Other characters are encoded
in hexadecimal.
"escape" also considers that you might want to include the escaped string in a larger string, so it appends a space if the escaped
string ends with a hexadecimal escape with fewer than six digits.
unescape $string
This turns something like "H65llo" into "Hello" (including quotes).
escape_ident $string
escape_ident $string, $more_chars_to_escape
This escapes $string as a CSS identifier, escaping also any characters matched by $more_chars_to_escape.
unescape_url $url_token
Returns the URL that the token represents.
escape_str $string
Returns a CSS string token containing $string (within quotes; characters possibly escaped).
unescape_str $string_token
Returns the value that a CSS string token represents.
