A simple reduction from the
Letter of Damar Wulan on
using Microsoft's Javanese Text
font and the Tuladha Jejeg webfont.
The underlying cause of the problem is that operating systems other Windows 8.1 do not ship a font
with Javanese support and the script requires complex text formatting which isn't consistently
available. Firefox has support for SIL's Graphite
and consistently looks correct on every platform. Chrome looks good on Windows 7+ but not OS X.
Safari is incorrect on OS X 10.9.
