This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
TextDecoder interface represents a decoder for a specific method, that is a specific character encoding, like
gbk, etc. A decoder takes a stream of bytes as input and emits a stream of code points. For a more scalable, non-native library, see
StringView – a C-like representation of strings based on typed arrays.
let win1251decoder = new TextDecoder('windows-1251'); let bytes = new Uint8Array([207, 240, 232, 226, 229, 242, 44, 32, 236, 232, 240, 33]); console.log(win1251decoder.decode(bytes)); // Привет, мир!
