UTF-16可看成是UCS-2的父集。在没有辅助平面字符（surrogate code points）前，UTF-16与UCS-2所指的是同一的意思。但当引入辅助平面字符后，就称为UTF-16了。现在若有软件声称自己支持UCS-2编码，那其实是暗指它不能支持在UTF-16中超过2字节的字集。对于小于0x10000的UCS码，UTF-16编码就等于UCS码。ASCII ...

UnlikeNSString, however,String.UTF16Viewdoes not use integer indices. If you need to access a specific position in a UTF-16 view, use Swift’s index manipulation methods. The following example accesses the fourth code unit in both theflowersandnsflowersstrings: ...

Because MySQL must allow for the worst case (that one character requires four bytes) the maximum length of autf16column or index is only half of the maximum length for aucs2column or index. For example, the maximum length of aMEMORYtable index key is 3072 bytes, so these statements create...
