Crash (IndexOutOfRangeException) at Avalonia.Media.GlyphRun.CreateGlyphRunMetrics When Selecting "Marlett" font

[Natestah]

Describe the bug

Added a Font Selector to my "text searching program" and got a crash. on selecting the "Marlett" font.

System.IndexOutOfRangeException: Index was outside the bounds of the array.

To Reproduce

I have created a Repository with an immediate repro of this issue in
https://github.com/Natestah/AvaloniaFontCrash

The above repository has all this, just grab that and run it.

Steps I followed:

1. Create a new Avalonia project
2. Set the windows Font to "Marlett"
3. Add a named TextBox
4. Add the following to the window loaded event:

        StringBuilder textbuilder = new StringBuilder();
        for (int i = 0; i < 256; i++)
        {
            textbuilder.Append((char)i);
        }
        TextBlock.Text = textbuilder.ToString();

Expected behavior

Non standard fonts should do a default behavior (unfound square visual?), but not throw here. I cannot guaranteed that user installed fonts will not crash the same way.

Avalonia version

11.0.6.0 ( this template ), first discovered in 11.1.0.0

OS

Windows
