fdo#67370: Hyphens are not visible in tagged PDF
One requirement of tagged PDF is to represent automatically inserted
hyphens using the soft hyphen (U+00AD) character, so we were doing this
by simply passing that character to text layout code when exporting a
tagged PDF (which is the literal suggestion of old PDF specification).
This is wrong, though, since the soft hyphen is a control character and
should not have a visible output by itself (and fonts might not even
have a visible glyph there), but this happened to work because non of
the layout engines we are using treated soft hyphen specially and was
just showing whatever glyph the font had there. This broke with the
switch to HarfBuzz since it will not show any visible glyph for Unicode
control characters (by default), which is the right thing to do.
Latest versions of PDF spec suggest using either ToUnicode mapping or an
ActualText text entry to encode the soft hyphen instead, I found it
easier to use ActualText since we already have code that handles
non-standard hyphenation using it already.
