字符串文字中的Swift特殊Unicode字符
[英]Swift Special Unicode Characters in String Literals
问题描述
Am trying to do the experiment the following in Swift, as its written in apple developer documentation: let encircledLetter: Character = "i\\u{20DD}" 
我试图在Swift中进行以下实验，正如它在Apple开发者文档中所写的那样： let encircledLetter: Character = "i\\u{20DD}"
But unfortunately the compiler is giving an error 但遗憾的是编译器发出错误
\u escape sequence expects 4 hex digits to follow it
I am totally new in Swift so I don't know if I missed something here 我是Swift的全新人，所以我不知道我是否错过了这里的一些东西
