, KOI8-R
, GBK
, etc. A decoder takes a stream of bytes as input and emits a stream of code points.
Note: This feature is available in Web Workers
Constructor
TextDecoder()
-
Returns a newly constructed
TextDecoder
that will generate a code point stream with the decoding method specified in parameters.
Instance properties
The TextDecoder
interface doesn’t inherit any properties.
TextDecoder.encoding
Read only-
A string containing the name of the decoder, that is a string describing the method the
TextDecoder
will use. TextDecoder.fatal
Read only-
A
Boolean
indicating whether the error mode is fatal. TextDecoder.ignoreBOM
Read only-
A
Boolean
indicating whether the byte order mark is ignored.
Instance methods
The TextDecoder
interface doesn’t inherit any methods.
TextDecoder.decode()
-
Returns a string containing the text decoded with the method of the specific
TextDecoder
object.
Examples
Representing text with typed arrays
This example shows how to decode a Chinese/Japanese character
, as represented by five different typed arrays: Uint8Array
, Int8Array
, Uint16Array
, Int16Array
, and Int32Array
.
let utf8decoder = new TextDecoder(); // default 'utf-8' or 'utf8'
let u8arr = new Uint8Array([240, 160, 174, 183]);
let i8arr = new Int8Array([-16, -96, -82, -73]);
let u16arr = new Uint16Array([41200, 47022]);
let i16arr = new Int16Array([-24336, -18514]);
let i32arr = new Int32Array([-1213292304]);
console.log(utf8decoder.decode(u8arr));
console.log(utf8decoder.decode(i8arr));
console.log(utf8decoder.decode(u16arr));
console.log(utf8decoder.decode(i16arr));
console.log(utf8decoder.decode(i32arr));
Handling non-UTF8 text
In this example, we decode the Russian text «Привет, мир!», which means «Hello, world.» In our TextDecoder()
constructor, we specify the Windows-1251 character encoding, which is appropriate for Cyrillic script.
const win1251decoder = new TextDecoder("windows-1251");
const bytes = new Uint8Array([
207, 240, 232, 226, 229, 242, 44, 32, 236, 232, 240, 33,
]);
console.log(win1251decoder.decode(bytes)); // Привет, мир!

Вместо русского «Яндекс» пишутся такие кракозябры «Ð¯Ð½Ð´ÐµÐºÑ»

Насколько я понял проблема с кодировкой в файле программы. Как вариант открыть через редактор нотепад++, скопировать весь код в буфер обмена, выставить нужную кодировку в разделе программы нотепад++ и вставить текст с буфера обмена.

Проблема в получаемых данных путем запроса, не отображаются русские символы через dump/alert

посмотри плз. Посмотрел. А почему именно мне вопрос?
Вместо русского «Яндекс» пишутся такие кракозябры «Ð¯Ð½Ð´ÐµÐºÑ» Не вместо, тут неправильное число символов.
как поменять кодировку, чтобы увидеть исходное значение??? Код JavaScript PS: Почему в теге с кодом нельзя нормально использовать юникодные символы?? Добавлено через 2 минуты

Случайно наткнулся на такой код:

ЗЫ вроде как эти кракозябры в Win1252 или еще чем-то. Нет, это просто байты с символах записаны…
