No need for the "size" variable

For your consideration, I suggest writing this sentence in terms of FontCache::lookupCTFont() (which calls CTFontCreateForCharactersWithLanguage() at the time of writing) instead of CTFontCreateForCharactersWithLanguage() since FontCache::systemFallbackForCharacters() does not explicitly call CTFontCreateForCharactersWithLanguage().

You may want to consider adding a comment to the code to explain that FontCache::lookupCTFont()/CTFontCreateForCharactersWithLanguage() will return a printer-friendly font.

With the removal of this size variable and associated logic the comment above fontManager is now out-of-date. Please update the comment above fontManager.

Going forward, the concept of a "printer font" will become less and less relevant. I don't think it's worth paying it any more lip service.
