    Allprint doesn't handle unicode input.  You'll need to 
    fix a lot more than the prototype to make it work.
    Lex in general doesn't work with UTF: the regular
    expression machinery it builds doesn't know about UTF.
    
    I don't understand the debug message fix -- what does
    negative input() return values mean?  I looked at the
    definition of input() that lex uses and I don't see
    it returning negative numbers.
