CoreText note: Client requested name ".SFCompact", it will get TimesNewRomanPSMT rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[UIFont systemFontOfSize:].
CoreText note: Set a breakpoint on CTFontLogSystemFontNameRequest to debug.
