Comment 3 for bug 1654904

Note: the font 'DFKai-SB' is no longer included with latest Windows 10 (see 'Products that supply this font' at https://www.microsoft.com/typography/fonts/font.aspx?FMID=1584 ).

I only have access to a Windows 10 computer, so I tested the reported issue with a rogue copy of version 5.00 of the font downloadable for free (as in beer) on the internets.

The issue reproduced with that font installed on OS X 10.7.5 with
- Inkscape 0.47 r22583 (official package, 2009)
and with all these local builds:
- Inkscape 0.48.5 r10040
- Inkscape 0.91 r13725
- Inkscape 0.92.0 r15299
- lp:inkscape/0.92.x r15309

Runtime (X11-based) dependencies used with all the tested builds except 0.47 (that build uses much older bundled dependencies from 2009):
- fontconfig 2.11.1
- freetype 2.6.3
- harfbuzz 1.2.5
- pango 1.38.1

Since the font seems to have been retired by Microsoft or replaced with other fonts - maybe a flaw in the font itself?
