Hello monks,

I have the same problem. Mine is a little bit different but in the case the same if I think of: "what delimiter for REGEX I can use?"

My problem has the following extension: I tried to use "§" as delimiter. This I did because I use REGEX on written text and I've found, that nearly any character including brackets will be able to be included in the text I want to process. Now for accident one of my tools has changed the encoding of a script to UTF-8 on upload to github, which was not originally. In the beginning I had Windows 1252 but this did work also under Unix/Linux. But now Perl recognizes a dangerous character before the "§":

Unrecognized character \xA7;

The code of the REGEX is as follows:

do { $foundstring =~ s§(<a |\[)([^<>\"]*)(<span class=\"foundterm\">)~~([^~]+)~~(</span>)§$1$2$4§igs;    } while $foundstring =~ m§(<a |\[)([^<>\"]*)(<span class=\"foundterm\">)~~([^~]+)~~(</span>)§is;

has someone an idea or a hint which character I can use and which is not needed to escape in the text?

Thanks in advance and regards

Extension:

I have done a workaround. To be able to use curly brackets as REGEX delimiters I've replaced curly brackets in the text before the operation and set it back afterwards.

	## hide out the curly brackets
	$foundstring =~ s|\{|#lcb#|igs;
	$foundstring =~ s|\}|#rcb#|igs;

	do { $foundstring =~ s{(<a |\[)(^<>\"*)()~~(^~+)~~()}{$1$2$4}igs;	} 
       while $foundstring =~ m{(<a |\[)(^<>\"*)()~~(^~+)~~()}is;

	## bring the curly brackets back
	$foundstring =~ s|#lcb#|\{|igs;
	$foundstring =~ s|#rcb#|\}|igs;

This means in the end it does not matter if someone saves the perl by accident in UTF-8, it will work nonetheless.
