sw: WW8 import: instead of control character insert '?' for footnote

SwWW8ImplReader::ReadChar() inserts a U+0002 control character to
temporarily mark a footnote anchor; this is then deleted and replaced
with a real footnote hint by SwWW8ImplReader::End_Footnote().

The assumption is that it is necessary to insert a placeholder
character to be able to apply formatting to it.

But if the document is corrupted, the control character could survive
the import, which sounds less than ideal.

So either make this magic character more explicit by documenting it in
hintids.hxx and removing any outstanding ones at the end of the import,
or use a non-offensive character instead; since this should only affect
invalid documents, choose the solution with the least effort.
