Convert ANSI file text into UTF8 in node.js usinf Fyle System
Solution 1
Of course, ANSI is not actually an encoding. But no matter what exact encoding we're talking about I can't see any Microsoft code pages included in the relatively short list documented at Buffers and Character Encodings:
ascii
- for 7-bit ASCII data only. This encoding is fast and will strip the high bit if set.utf8
- Multibyte encoded Unicode characters. Many web pages and other document formats use UTF-8.utf16le
- 2 or 4 bytes, little-endian encoded Unicode characters. Surrogate pairs (U+10000 to U+10FFFF) are supported.ucs2
- Alias of 'utf16le'.base64
- Base64 encoding. When creating a Buffer from a string, this encoding will also correctly accept "URL and Filename Safe Alphabet" as specified in RFC4648, Section 5.latin1
- A way of encoding the Buffer into a one-byte encoded string (as defined by the IANA in RFC1345, page 63, to be the Latin-1 supplement block and C0/C1 control codes).binary
- Alias for 'latin1'.hex
- Encode each byte as two hexadecimal characters.
If you work in Western Europe you may be tempted to use latin1
as synonym for Windows-1252 but it'll render incorrect results as soon as you print a €
symbol.
So the answer is no, you need to install a third-party package like iconv-lite.
Solution 2
In my case the convertion between types was due to the need to use special latin characters as 'í' or 'ó'. I solve it changing the encoding from 'utf8' to binary in the fs.readFile() function:
fs.readFile('..\\LogSSH\\' + fileName + '.log', {encoding: "binary"}, function (err, data) {
if (err) {
console.log(err);
}

I´m trying to convert the text from an ANSI encoded file to an UTF8 encoded text in node.js.
I´m reading the info from the file using node´s core Fyle System. Is there any way to 'tell' to readFile that the encoding is ANSI?
fs = require('fs'); fs.readFile('..\\\\LogSSH\\' + fileName + '.log', 'utf8', function (err, data) { if (err) { console.log(err); }
If not, how can I convert that text?

Duncan Lukkenaer over 6 years@AsierPomposo How did you solve it without iconv-lite?

Asier Pomposo over 6 years@DuncanLuk . I solve it changing the encoding from 'utf8' to binary in the fs.readFile(). you have the code I used above
