in reply to replacing close-single-quote with apostrophe
You can use the \x notation in a regex:
s/\xe2\x80\x99/'/g
If you want to use it in a one-liner, you need to be careful about quoting. In bash, for example, you need to write
perl -pe 's/\xe2\x80\x99/'\''/g' file
or use the \x for the single quote, as well:
perl -pe 's/\xe2\x80\x99/\x27/g' file
Alternatively, if you want to use "smart quote" directly:
use utf8; open my $in, '<:encoding(UTF-8)', 'file' or die $!; while (<$in>) { s/’/'/g; print; }
map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
