    TextEncoder()

    This is an experimental technology
    Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use 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 spec changes.

    The TextEncoder() constructor returns a newly created TextEncoder object for the encoding specified in parameter.

    Syntax

    encoder = new TextEncoder(utfLabel); 
    

    Parameters

    utfLabel
    Is a DOMString containing the label of the encoder. Each label is associated with a specific encoding type:
    Possible values of utfLabel Encoding
    "unicode-1-1-utf-8", "utf-8", "utf8" 'utf-8'
    "utf-16be" 'utf-16be'
    "utf-16", "utf-16le" 'utf-16le'

    Exceptions

    • RangeError is thrown if utfLabel is not one of the supported values.

    Example

    var textEncoder = new TextEncoder("unicode-1-1-utf-8");
