It looks like labels with Chinese characters will have an extra sublayer (not subviews).

When I add two UILabels to a view, one with English characters and one with Chinese, there are slightly different hierarchies.

0x7fd3b972c020 is the UILabel with English characters:

(lldb) po [[0x7fd3b972c020 layer] sublayers]
 nil
(lldb) po [0x7fd3b972c020 layer]
<_UILabelLayer:0x7fd3b972c2b0; position = CGPoint (187.5 333.75); bounds = CGRect (0 0; 133 20.5); delegate = >; contents = ; opaque = YES; allowsGroupOpacity = YES; rasterizationScale = 2; contentsScale = 2>

0x7fd3b95208f0 is the UILabel with Chinese characters:

(lldb) po [[0x7fd3b95208f0 layer] sublayers]
(
<_UILabelContentLayer:0x7fd3bb0e0a60; position = CGPoint (68.25 11); bounds = CGRect (0 0; 140.5 29); contents = ; allowsGroupOpacity = YES; rasterizationScale = 2; contentsScale = 2>
)


(lldb) po [0x7fd3b95208f0 layer]
<_UILabelLayer:0x7fd3b950ba70; position = CGPoint (187.5 361.75); bounds = CGRect (0 0; 136 20.5); delegate = >; sublayers = (<_UILabelContentLayer: 0x7fd3bb0e0a60>); opaque = YES; allowsGroupOpacity = YES; rasterizationScale = 2; contentsScale = 2>

Each of the views have opaque enabled with white background colors.
