Here's one (for Lua5.1) which isn't very good :)

 function utf8tolatin1(s)
  return (s:gsub("([\192-\255])([\128-\191]*)", function(head, tail)
    if head == "\194" and #tail == 1 then
      return tail
    elseif head == "\195" and #tail == 1 then
      return string.char(tail:byte()+64)
    else return "?"
    end
  end))
end


It does too little error checking, and it doesn't combine diacritics 
(i.e. n + combining ~ does not become ñ). So it's only virtue is that 
it fits in a short email message.
