We have been using this in our production code for 6 years, and it has worked flawlessly. Note, however, that escape() and unescape() are deprecated. See this.

AlbertAlbert 62.7k58 gold badges229 silver badges367 bronze badges 3 Perhaps using the textDecoder will be sufficient. Not supported in IE though.
Handling non-UTF8 textIn 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.
The interface for the TextDecoder is described here. Retrieving a byte array from a string is equally simpel:
If you have it in a different encoding then you must compensate for that upon encoding. The parameter in the constructor for the TextEncoder is any one of the valid encodings listed here. answered Nov 17, 2016 at 9:53

1 This is what I found after a more specific Google search than just UTF-8 encode/decode. so for those who are looking for a converting library to convert between encodings, here you go. https://github.com/inexorabletash/text-encoding
Paste from repo readme All encodings from the Encoding specification are supported: utf-8 ibm866 iso-8859-2 iso-8859-3 iso-8859-4 iso-8859-5 iso-8859-6 iso-8859-7 iso-8859-8 iso-8859-8-i iso-8859-10 iso-8859-13 iso-8859-14 iso-8859-15 iso-8859-16 koi8-r koi8-u macintosh windows-874 windows-1250 windows-1251 windows-1252 windows-1253 windows-1254 windows-1255 windows-1256 windows-1257 windows-1258 x-mac-cyrillic gb18030 hz-gb-2312 big5 euc-jp iso-2022-jp shift_jis euc-kr replacement utf-16be utf-16le x-user-defined (Some encodings may be supported under other names, e.g. ascii, iso-8859-1, etc. See Encoding for additional labels for each encoding.) answered Feb 26, 2019 at 10:33

MCCCSMCCCS 9723 gold badges18 silver badges42 bronze badges This is a solution with extensive error reporting. It would take an UTF-8 encoded byte array (where byte array is represented as array of numbers and each number is an integer between 0 and 255 inclusive) and will produce a JavaScript string of Unicode characters.

I reckon the easiest way would be to use a built-in js functions decodeURI() / encodeURI().

I searched for a simple solution and this works well for me:
Only issue I have is sometimes I get one character at a time. This might be by design with my source of the arraybuffer. I'm using https://github.com/xseignard/cordovarduino to read serial data on an android device.

1 How do you decode or encode a URL in JavaScript?Decoding in Javascript can be achieved using decodeURI function. It takes encodeURIComponent(url) string so it can decode these characters. 2. unescape() function: This function takes a string as a single parameter and uses it to decode that string encoded by the escape() function.
What is decodeURI in JavaScript?The decodeURI() function decodes a Uniform Resource Identifier (URI) previously created by encodeURI() or by a similar routine.
How do I use encodeURI in JavaScript?The encodeURI() method encodes a URI.. Note. Use the decodeURI() method to decode a URI.. Special Characters. The encodeURI() method does not encode characters like: , / ? : @ & = + $ * # ... . See Also: The encodeURIComponent() method to encode a URI. The decodeURIComponent() method to decode a URI.. How do you decode a space in a URL?URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
