Re: [ft] Glyph 0xBB does not load from TTF-FreeFont FreeSerif.ttf since 6.12.2

Dear Volker,

Thank you for reporting, your issue seems to be same with
the issue discussed in "Failure in loading U+033F in DejaVu fonts".

I think the latest git head fixes this issue. If possible,
please test. I tested by myself and the issue seems to be
fixed.

Regards,
