Two small fixes

[Dekel Tsur]

1. If a line in the TOC contains %, it will not appear in the TOC menu
(as % is a special char for popups).
If fixed this bug by replacing each '%' char by '%%'
(actually, in XForms0.88 this doesn't work, so I'm replacing '%' by '?'.
Please check if the fix is OK with XForms0.89).

2. Correct drawing of accents (macron) when using iso10646-1 font.
