I posted a question on Stack Overflow a few days ago, I'm wondering whether someone might want to take a look:

  http://stackoverflow.com/questions/5144862/escape-pipe-character-in-org-mode

The issue is that I've got tables whose cells contain the '|' character (it's a table of regular expressions), and I can't seem to figure out how to escape it so that it doesn't mean a delimiter between cells.  Anyone have advice or a pointer to the docs I can't seem to find?

Thanks.

  I guess it all depends on what you want to do with the resulting
  document.  You could always insert a character that looks like the '|'
  character, such as the unicode "LIGHT VERTICAL BAR" (0x2758) character,
  '❘', and I'm sure there are others that could be used... org should
  ignore this character as a table delimiter.

    Thanks Eric.  That's not a great solution in this case, because in order
    to work in a regex it needs to be the character '|', 0x7C.
    
    Is there some way to put in characters by ASCII code maybe?

  I don't think you can.

    I'm making slight progress, actually.
    
    On StackOverflow 
    (http://stackoverflow.com/questions/5144862/escape-pipe-character-in-org-mo
    de), it was suggested to use the \vert{} character escape, which does
    work.  
    
    However, since this is code (a regular expression), I want it to appear
    monospaced, so I'm not out of the woods yet - here's a test case that
    shows my intent:
    
      | foo | =m/foo\vert{}foodfight/= |
    
    The \vert{} seems not to work inside a =...= construction.  Furthermore,
    the =...= construction is problematic there because it conflicts with the
    start-of-formula syntax.

      =...= is used for code so it is printed as it written
      You may use \texttt{}
      | foo | \texttt{m\/foo\vert{}foodfight\/} |
      
      I don't have emacs right now so I can test it... but it should work

        Unfortunately that doesn't work when exporting to HTML though, I assume
        it's for LaTeX export only?
        
        
        I'd suggest there are 3 things that need to be addressed/fixed in org-mode.
        
        First, the table-parser should respect =...= sections and skip over them,
        just like a C preprocessor respects double-quoted string sections.
        
        Second, there should be a way to indicate verbatim sections that doesn't
        conflict with formula syntax.
        
        Finally, there should be a way (e.g. \x{...}) to stick in a character by
        ASCII/Unicode number.  This would help with several issues when a literal
        character is intended but it conflicts with a markup character.
