 已知问题
 ==============
-* YYText 并不能支持所有 CoreText/TextKit 的属性，比如 NSBackgroundColor、NSStrikethrough、NSUnderline、NSAttachment、NSLink 等，但 YYText 中基本都有对应属性作为替代。详情见上方表格。
+* YYText 并不能支持所有 CoreText/TextKit 的属性，比如 NSBackgroundColor、NSStrikethrough、NSUnderline、NSAttachment、~~NSLink~~ 等，但 YYText 中基本都有对应属性作为替代。详情见上方表格。
 * YYTextView 未实现局部刷新，所以在输入和编辑大量的文本（比如超过大概五千个汉字、或大概一万个英文字符）时会出现较明显的卡顿现象。
 * 竖排版时，添加 exclusionPaths 在少数情况下可能会导致文本显示空白。
 * 当添加了非矩形的 textContainerPath，并且有嵌入大于文本排版方向宽度的 RunDelegate 时，RunDelegate 之后的文字会无法显示。这是 CoreText 的 Bug（或者说是 Feature）。
