There REALLY IS a "maybe", because this is not required at all, and most
chess applications do not use any "font" (most of them display bitmap
icons, or custom 2D/3D graphics)

What ??? Black herring here !

Non sense reply !!! Custom fonts are hard to integrate as they depend on
renderers (which most applications don't want to support directly, they are
part of a browser or OS). And OpenType fonts are much less flexible for
what applications want to do. SVG allows much easier variations and
effects. There are tons of tools or stylesheets for that, which will not
work on glyphs in OpenType fonts.

You were yourself speaking about applications, me too, not just a "game".
