[PATCH] Source_file: remove mbrtowc() in favor of utf8_char_len()

[Patrick McCarty]

Hello,

I have uploaded a patch series to Rietveld for review:

  http://codereview.appspot.com/154046/show

This addresses the following report:

  http://lists.gnu.org/archive/html/bug-lilypond/2009-10/msg00001.html

and keeps compatibility with the initial fix I made for this report:

  http://lists.gnu.org/archive/html/bug-lilypond/2009-10/msg00049.html


The discussions from the archives provide a lot of background on the
issues.  Please let me know if you have any suggestions or know of an
easier approach.


Thanks,
Patrick
