I need to output a company name and legal requires that we put the
circle R after the name as in Zowcorp(R).  In some other cases we need
the trademark (TM) symbol.

I did this to try to find them: 

(0..255).each {|i|
  puts i.to_s+" "+i.chr
}

But I didn't find them in there... Which makes me wonder if it's even
possible to output them this way.  I know that to get them in HTML you
use ® and ™
