A Node.js module to convert MARC8 encoded string to UTF-8.

Installation

npm install marc8

Usage

var marc8 = require('marc8');

var options = {
    normalization: 'NFC',
    invalid: 'replace',
    replace: '',
    expandNCR: false
};

marc8(marc8_string, options);

Options

the options parameter is optional. If used, the following options can be set.

• normalization: by default return NFC normalized, but set :normalization option to: "NFC", "NFD", "NFKC", "NFKD", or false. Set to false for higher performance.
• expandNCR: By default, escaped unicode 'named character references' in Marc8 will be translated to actuall UTF8. Eg. "‏". But pass expandNCR: false to disable.
• invalid: Bad Marc8 bytes? By default will throw an error message. Set option invalid: "replace" to instead silently replace bad bytes with a replacement char -- by default Unicode Replacement Char, but can set option replace to something else include empty string.
• replace: used with the option invalid. For example: marc8(bad_marc8, {invalid: "replace", replace: "")

Example

var marc8 = require('marc8');

var marc8Str = "Conversa\xF0c\xE4ao \xC1";
var unicodeStr = "Conversação \u2113";

var converted = marc8(marc8Str);

console.log(converted === unicodeStr); // will print true
