他们打算叫它"Universal Multiple-Octet Coded Character Set",简称UCS, 俗称 "UNICODE"。这就是Unicode,就像它的名字都表示的,这是一种所有符号的编码! UNICODE统一了各国,成为了实事上的大一统的编码规范。这种编码非常大,大到可以容纳世界上任何一个文字和标志。所以只要电脑上有 UNICODE 这种编码系统,无论是全球...
U+FFFD,即替换字符(Replacement Character),只是Unicode表中的另一个码位。应用程序和库可以在检测到Unicode 错误时使用它。 如果将码位的一半切掉,那么另一半也就没什么用了,除了显示错误。这时就会使用�。 JS 版本 const text = "前端柒八九"; const encoder = new TextEncoder(); const bytes = encoder....

The Unicode character 💩 Pile of Poo (U+1F4A9) in UTF-16 must be encoded as a surrogate pair, i.e. two surrogates. To convert any code point to a surrogate pair, use the following algorithm (in JavaScript). Keep in mind that we're using hexidecimal notation....
