There's a trick you can do to convert those characters. Turns out there is. The decodeURIComponent function used above will throw an error if given a malformed encoded sequence. The problem is that once the page is served up, the content is going to be in the encoding described in the content-type meta tag.
The content in "wrong" encoding is already garbled. You're best to do this on the server before serving up the page. Or as I have been know to say: UTF-8 end-to-end or die. After, it's almost impossible to reliably work with that string. For example:. Seems like the magic is happening on readAsBinaryString so maybe someone can shed some light on why this works. If you do that, jQuery should already have interpreted them properly by the time you access the deserialized objects. There are libraries that do charset conversion in Javascript.
But if you want something simple, this function does approximately what you want:. Now, keep in mind that some apps do accept UTF-8 encoding, but they can't guess the encoding unless you prepend a BOM character, as explained here.

At its most basic, data on the Internet consists of groups of 8-bits known at an "octet", but usually just called a "byte". Obviously to represent character data we need a mapping between numeric values and characters. This defines alphanumeric characters: A-Z, a-z, , command characters such as carriage return and backspace, and assorted special characters. Of course, using 8 bits you can represent characters, but this isn't enough to represent all of the characters used by even a small selection of the written languages of the world.
The first solution to this problem was to simply reuse the same numeric codes and associate them with different sets of characters. The most commonly used on the Internet is ISO n where n is between 1 and Each value of n maps a different set of characters onto the 0 to values that a byte can represent. Notice that we now have a situation where a single character code can correspond to different characters depending on which ISO character set is selected. This is a potential problem if a server sends data using one ISO character set and the browser displays it using another.
The data hasn't changed, but what is displayed on each system is different. To stop this from happening, servers send a header stating the character set in use. For example:. The problem with this is that the server can't adjust its headers for an individual page. Setting the HTTP header for an entire site is reasonable, but you still might want to send a page in another character set. Unicode can be implemented by different character sets.
Because the character sets in ISO were limited in size, and not compatible in multilingual environments, the Unicode Consortium developed the Unicode Standard. The Unicode Standard covers almost all the characters, punctuations, and symbols in the world. Unicode enables processing, storage, and transport of text independent of platform and language. Unicode is a list of characters with unique decimal numbers code points. UTF-8 encoding will store "hello" like this binary : Encoding translates numbers into binary.
Character sets translates characters to numbers.
