ibm866

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:

npm install ibm866

In a browser or in Node.js:

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

API

ibm866.labels

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

ibm866.encode(input, options)

This function takes a plain text string (the input parameter) and encodes it according to ibm866. The return value is a ‘byte string’, i.e. a string of which each item represents an octet as per ibm866.

const encodedData = ibm866.encode(text);

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

const encodedData = ibm866.encode(text, {
  mode: 'html'
});
// If `text` contains a symbol that cannot be represented in ibm866,
// instead of throwing an error, it will return an HTML entity for the symbol.

ibm866.decode(input, options)

This function takes a byte string (the input parameter) and decodes it according to ibm866.

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'.

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.

For decoding a buffer (e.g. from fs.readFile) use buffer.toString('binary') to get the byte string which decode takes.

Notes

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