When importing non-XML documents with foreign or special characters
they may contain Unicode expressions such as \u00e9 since they were
not processed by liblouisutdml. I have a routine to find the
corresponding codepoints and display the corresponding character. I
haven't done much testing yet but I guess that when saving as UTD
these should be processed correctly.
