      I hope in the actual specification text we can
          be
          precise about character counting.  As we all know, with XML
          we're
          dealing with lexical strings, which might include character
          entities, as
          well as parsed XML where there is Unicode characters, but even
          then there
          are different conventions of dealing with composition
          sequences, etc.  We
          probably want to cite a specific Unicode normalization form to
          do the counting
          on:
      

      

      http://www.w3.org/TR/2005/WD-charmod-norm-20051027/
      

      

      It looks like "Form C" is what the W3C is
          recommending for processing, but I am not certain:

      Note:  This came up in the OpenFormula
          discussions,
          since we have spreadsheet functions that deal with extracting
          substrings
          at given offsets.  In that case, implementations diverged
          enough that
          we were only able to mark some functions as
          "normalization-sensitive",
          a form of implementation-dependent behavior.  I really hope
          that with
          CT, since we're starting fresh, we can specify exactly what
          normalization
          form to use.
      

      

    
    Good point and thanks for the references. I will have a look into
    them.
