  Based on the analysis above, it seems that, after colapsing \ci/,
  \cy/, \cg/, \cs/, and the tall characters \[lq]j/ to `H' \[lq]g/ to
  `P', we can parse most strings consisting of `c', `z', `H', and `P'
  into the following "letters" (the frequencies are for isolated
  occurences only):

  There are some nice things in this table: \ccc/ = `O' and \cscc/ = `A' come out similar, and same for \cc/ = `M' and \csc/ = `R'.
  
  There are some surprises, such as the similarity between \qg,lg/ = `P' and \cg/ = `8'; or between \lj,qj/ = `E', \cs/ = `Z',
  and \is/ = `r'. 

  The slight differences between members of the same class may be telling us something, too.
  
    \cc/ and \csc/   are similar, but 
                     only \cc/ is followed by \lj/, \qj/, \cs/, or \ix/
    
    \ccc/ and \cscc/ are similar, but 
                     only \ccc/ is followed by \lg/, \qg/, or \cs/
                     only \cscc/ is followed by \ljcc/ or \qjcc/
                     
    \ljc/ and \ljcc/ are similar, but 
                     only \ljc/ is followed by unparsed \c/
                     only \ljcc/ can be preceded by \cscc/
                     
  Also, \cgci/ is probably a letter; indeed \cg/ is followed by \ci/ 91% of the time, although \ci/
  occurs in other contexts too. 

  What can we conclude from these bits, really?
