Re: [csswg-drafts] [css-fonts] Consider specifying UA should not perform system fallback for Unicode PUA

> How would the (U+F8FF Apple Logo) character work? I don’t think anyone explicitly lists the specific font it’s in.

I guess if we standardize the recommendation as "should", you could make an exception for U+F8FF? Or use 🍏 + VS15? Or propose to standardize something in Unicode, e.g. GENERIC CORP LOGO + TAG SEQUENCE...TAG TERM for corporate logos? 

On a more serious note: The background for this proposal is that the PUA semantics are defined to be custom to the font - using system wide fallback for them is highly unlikely to return meaningful results to avoid .notdef's.

[We're implementing it in Blink]( after we discovered that we occasionally receive unsuitable fallback results from the system when querying for PUA codepoints while for example a web icon font has not loaded yet.
