On Windows 10 I have the following WPF TextBlock:
<TextBlock FontFamily="Segoe Mdl2 Assets">Hello World!</TextBlock>
The text is rendered as empty rectangles (undefined glyphs).
My understanding from this page on MSDN is that a fallback should be substituted.
Font Fallback
Font fallback refers to the automatic substitution of a font other than the font that is selected by the client application. There are two primary reasons why font fallback is invoked:
•The font that is specified by the client application does not exist on the system.
•The font that is specified by the client application does not contain the glyphs that are required to render text.
Is it possible to make this work without resorting to checking manually as in Is there a way to programmatically determine if a font file has a specific Unicode Glyph?
