Fonts have nothing to do with it; they’re an aspect of rendering text, not of working with the text in memory. (If it weren’t this way, you wouldn’t be able to work with NSString at all; everything would have to be based on NSAttributedString to carry around the font info for every character.) The bicycle is a well-defined Unicode character, an emoji. When it comes time to render it, the typesetter will look for a glyph in the current font for that character code. It probably won’t find one, so it will go through a series of fallback fonts looking for a glyph until it finds one in whatever internal font stores the emoji glyphs. Then it uses that font to render it. This is the same process that allows you to put Japanese or Cyrillic characters in a string and render them in Helvetica or Papyrus even though those fonts don’t support those character sets. They’re actually being rendered in whatever system font is the default for those character sets. This is all invisible to you unless you start diving down into the NSTypesetter or CoreText APIs. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
