我需要读取一个用ISO-8859-1(也称为latin1)编码的文件,如下所示:

var file_contents = fs.readFileSync("test_data.html", "latin1");

但是,Node报错“latin1”或“ISO-8859-1”不是有效的编码

使用iconv-lite重新编码文件:

var iconvlite = require('iconv-lite');
var fs = require('fs');

function readFileSync_encoding(filename, encoding) {
    var content = fs.readFileSync(filename);
    return iconvlite.decode(content, encoding);
}

或者,使用iconv

var Iconv = require('iconv').Iconv;
var fs = require('fs');

function readFileSync_encoding(filename, encoding) {
    var content = fs.readFileSync(filename);
    var iconv = new Iconv(encoding, 'UTF-8');
    var buffer = iconv.convert(content);
    return buffer.toString('utf8');
}

可以使用以下纯节点代码获得相同的结果。

npm install iconv
