165: How do I view text with embedded underlining (eg., ClariNews)?
  
  Underlining appears like this:
  
    _^Hu_^Hn_^Hd_^He_^Hr_^Hl_^Hi_^Hn_^Hi_^Hn_^Hg
  
  You can destructively remove underlining with M-x ununderline-region.
  
  For ClariNews articles, clari-clean.el by David N. Blank-Edelman
  <dnb@meshugge.media.mit.edu> will remove both underlining and overstriking
  automatically.
