 # This tag can be used to specify the character encoding of the source files
 # that doxygen parses. Internally doxygen uses the UTF-8 encoding, which is
 # also the default input encoding. Doxygen uses libiconv (or the iconv built
 # into libc) for the transcoding. See http://www.gnu.org/software/libiconv for
 # the list of possible encodings.
