ibm866  

_ibm866_ is a robust JavaScript implementation of the ibm866 character encoding as defined by the Encoding Standard.

This encoding is known under the following names: 866, cp866, csibm866, and ibm866.

Installation

Via npm:

``bash
npm install ibm866
`

In a browser or in Node.js:

`js
import {encode, decode, labels} from 'ibm866';
// or…
import * as ibm866 from 'ibm866';
`

API

$3

An array of strings, each representing a label for this encoding.

$3

This function takes a plain text string (the input parameter) and encodes it according to ibm866. The return value is an environment-agnostic Uint16Array of which each element represents an octet as per ibm866.

`js
const encodedData = ibm866.encode(text);
`

The optional options object and its mode property can be used to set the error mode. The two available error modes are 'fatal' (the default) or 'replacement'. (Note: This differs from the spec, which recognizes “fatal” and HTML” modes for encoders. The reason behind this difference is that the spec algorithm is aimed at producing HTML, whereas this library encodes into an environment-agnostic Uint16Array of bytes.)

`js
const encodedData = ibm866.encode(text, {
mode: 'replacement'
});
// If text contains a symbol that cannot be represented in ibm866,
// instead of throwing an error, it becomes 0xFFFD.
`

$3

This function decodes input according to ibm866. The input parameter can either be a Uint16Array of which each element represents an octet as per ibm866, or a ‘byte string’ (i.e. a string of which each item represents an octet as per ibm866).

`js
const text = ibm866.decode(encodedData);
`

The optional options object and its mode property can be used to set the error mode. For decoding, the error mode can be 'replacement' (the default) or 'fatal'.

`js
const text = ibm866.decode(encodedData, {
mode: 'fatal'
});
// If encodedData contains an invalid byte for the ibm866 encoding,
// instead of replacing it with U+FFFD in the output, an error is thrown.
``

Notes

Similar modules for other single-byte legacy encodings are available.
