in reply to This looks like whitespace in my CSV but doesn't seem to be

You've got blurry vision

#!/usr/bin/perl -- use strict; use warnings; use Text::CSV; use Data::Dump; open my $io, '<', \q{ "My Company","Gavin","Henry ","ghenry@ghenry.co.uk"," 1.00" }; my $csv = Text::CSV->new( { binary => 1, eol => $/ } ); while ( my $row = $csv->getline($io) ) { my @fields = @$row; next unless $fields[4]; dd \@fields; $fields[4] =~ s/\s+//g; print $fields[4], "\n"; dd \@fields; } __END__ ["My Company", "Gavin", "Henry ", "ghenry\@ghenry.co.uk", " 1.00"] 1.00 ["My Company", "Gavin", "Henry ", "ghenry\@ghenry.co.uk", "1.00"]

    That gives me:

    [ "My Company", "Gavin", "Henry\xC2\xA0", "ghenry\@ghenry.co.uk", "\xC2\xA1.00", ]

    which isn't whitespace after all. Thanks for the Data::Dump tip. I've always used Data::Dumper. Swapping for that produces:

    $VAR1 = [ 'My Company', 'Gavin', 'Henry ', 'ghenry@ghenry.co.uk', ' 1.00' ]; $VAR1 = [ 'My Company', 'Gavin', 'Henry ', 'ghenry@ghenry.co.uk', ' 1.00' ];

    i.e.

    next unless $fields[4]; print Dumper \@fields; $fields[4] =~ s/\s+//g; print Dumper \@fields;

      Or is that hex for whitespace? Will check...

      \xC2\xA0 is a Unicode non-breaking space encoded into UTF-8. If you decode your UTF-8 string into a native Perl Unicode string (see Encode), and then add the /u modifier to your regular expression, that ought to enable \s to remove non-ASCII whitespace.

      perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

        That will be why Vim isn't allowing me either to do :%s/\s//g in that field.

        Excellent catch!

        I need to get a newer perl as I'm on 5.10.1 and /u throws an error.

        Cheers though, will look how I can do this.

      I don't work with multi-byte characters or UTF-8 files. But Perl has an amazing ability to deal with these things.

      From the open() docs, it could be that all you need to do is open the file in the right encoding mode and that could enable even Perl 5.10.X to work. I don't know for sure, but this idea is worth a try.

      open(my $fh, "<:encoding(UTF-8)", "filename") || die "can't open UTF-8 encoded filename: $!";

        Of course Marshall!!!

        That was it, all solved and s/^\s// works as I'd expect. Thanks so much. Very basic of me not to do.
