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

Restricting fallback for whole PUA right in the spec is too broad. There are system fonts covering legacy encodings, like SimSun-ExtB or Mingliu-HKSCS. Logic to fallback or not to fallback to them depends on the OS, document, user settings or maybe something else. 

I understand potential problems with falling back to icon fonts where it is not desirable. This may happen if you are "carelessly" harvesting all installed fonts for any character, including PUA. But this doesn't have to be done this way.
