writerfilter: rtftok: filter control characters
... in RTFDocumentImpl::checkUnicode(); see ooo86460-1.xls [sic]
for an example.
There is another caller of text() in rtfdispatchdestination.cxx:311 but
it turns out that buffered text was created by text() in the first
place.
This shouldn't be a problem for DOCX because XML 1.0 doesn't allow the
bad control characters anyway so the sax parser should report an error
in that case.
(cherry picked from commit a6516c76c01b92f7d35bfb352b63af7de42b5707)
