in reply to A little win

:'<,'>!perl -pe 'chomp; $_ =~ s/[<>]*//g; $_ = join "", map { chr $_ } + split ",", $_'

Could be written more simply and efficiently as:

:'<,'>!perl -pe 'chomp; tr/<>//d; $_ = join "", map chr, split /,/'

    Combine that with tye's suggestion and we're down to:

    :'<,'>!perl -pe 'tr/<>//d; $_ = pack "C*", split ","'

        ... simplicity wins again.

      Please read perldoc -f split, as the first argument to split is usually a regex, not a string

      :'<,'>!perl -pe 'tr/<>//d;$_=pack"C*",split/,/'

      Enjoy, Have FUN! H.Merijn

        Good point! I'll try to remember this from now on.

Discipulus is Corion reading 'Gory details of parsing quoted constructs'?..
[perldigious]: That's awesome erix. One of my work friends, who coincidentally convinced me to learn Perl originally, has a Finnish pen-pal. I showed him this and he immediately wanted to send it along to her.
[perldigious]: Also coincidentally, I'm currently in the middle of a winter storm that has dropped 1 foot of snow and is expected to drop another. I might have to adapt this for customers/vendors who come visit and put it at the beggining of every presentation I give.
[Discipulus]: the photo was removed... Cyrano de Berjerac was not of the same idea..
