 Set MGLIdeographicFontFamilyName in your containing application's Info.plist to
 font family name(s) that will be available at run time, such as “PingFang TC”
 or “Marker Felt”. This plist key accepts:
 
 - A string value of a single font family name.
 
 - An array of font family names. Fonts will be used in the defined order,
 eventually falling back to default system font if none are available.
 
 - A boolean value NO to disable client-side rendering of CJK glyphs —
 remote fonts specified in your style will be used instead.
