I have written s small patch based on pango_parse_markup (). It outputs
UTF-8 string without markup and entities are replaced too. The
differences in output are shown in the following diff:

A problem that is left is, that the filling-stuff doesn't fully work for
special characters with UTF-8 output. Maybe you have some idea.

What's your opinion about this patch?
