Re^4: Escape special characters for a LaTeX file

[Laurent_R]

Try to use the quotemeta operator (or, equivalently, the \Q ... \E tags) on your search list. It should remove all problems of this sort.

Another way to completely defeat scalar or array interpolation in regexes (as in strings) is by use of  ' (single-quote) delimiters for the  s/// substitution:

c:\@Work\Perl\monks\marek1703>perl -wMstrict -le
"my $s = '-#-$-%-&-~-_-}-{-^-0-$%&~_}{^0';
 print qq{'$s'};
 ;;
 $s =~ s' (?= [#$%&~_{}^]) '\\'xmsg;
 print qq{'$s'};
"
'-#-$-%-&-~-_-}-{-^-0-$%&~_}{^0'
'-\#-\$-\%-\&-\~-\_-\}-\{-\^-0-\$\%\&\~\_\}\{\^0'

(This applies also to  m// and  qr// operators.) See perlop.

Interesting, I did not know that.
