Duotone icons not working on web

[k-ane]

Testing on web, duotone icons are not showing up, I get this error:
Could not find a set of Noto fonts to display all missing characters. Please add a font asset for the missing characters.

Seemed to work great on MacOS so issue is restricted to web as far as I can tell.

For some added context, the issue only occurs with canvaskit. When using --web-renderer html the duotone icons load fine. May be a Flutter issue not an issue of this package

Hi @k-ane. This appears to be related to this open Flutter bug, in which CanvasKit is unable to render glyphs outside of the BMP (Basic Multilingual Plane) of Unicode. It does not appear to be solved, and the solution everyone seems to take is the same you have said above, using the html renderer.
