escaping characters in as3 as javascript does

Question

I am having trouble escaping special characters in as3.

trace( escape("who are ü?") );

returns who%20are%20%uFFFD%3F

or

trace( encodeURIComponent("who are ü?") );

returns who%20are%20%EF%BF%BD%3F

while in javascript this

alert( encodeURIComponent("who are ü?") );

returns who%20are%20%C3%BC%3F

and

alert( escape("who are ü?") );

returns who%20are%20%FC%3F

Any suggestions how to get as3 to return escaped special characters as javascript is? Why is as3 apparently choking?

Answer 1

Looks like AS is escaping the string as UTF-16, while the Javascript example is escaping as UTF-8. escape doesn't define how to deal with non-ascii characters, and so it's been deprecated as of JavaScript 1.5. You should use the function encodeURIComponent instead, which is defined as escaping as UTF-8 - This should be consistent across different implementations. If you require the AS behaviour, I don't think there is a native function in Javascript, but you can use the functions provided here .

尽管我的IDE（intellij）正在显示，保存和加载特殊字符，但它们仍保存在1252中。切换到UTF-8可以解决此问题。
