Some Segoe MDL2 Asset glyphs are unable to render in WinUI3 on Windows 10

[HO-COOH]

Describe the bug

I have a screenshot with WinUI3 (left) vs UWP (with WinUI2, right).

It shows all the glyphs listed here and I did not specify FontFamily on FontIcon on both cases (so according to the doc, it should be both using the same Segoe MDL2 Assets, I guess). Some glyphs on the WinUI3 side are unable to render as you can see.

Steps to reproduce the bug

This is the broken AddNewLine glyph.

        <Button Padding="0">
            <FontIcon Glyph="&#xF7B7;"/>
        </Button>

Expected behavior

Thanks for reporting this. I noticed the WASDK version is 1.4. Does this repro with 1.5 or the 1.6 previews? Does it repro on Windows 11?

This seems to be a font issue on win10 builds. I've shared the info with the appropriate team. @HO-COOH Thanks for reporting.
