在NodeJS中将字符串从utf8转换为latin1 [英] Converting a string from utf8 to latin1 in NodeJS

问题描述

我使用的是Latin1编码的数据库，不能将其更改为UTF-8，这意味着我遇到某些应用程序数据的问题。我使用Tesseract OCR一个文件（tesseract以UTF-8编码），并尝试使用iconv-lite;但是，它创建一个缓冲区并将该缓冲区转换为一个字符串。但是再次，缓冲区到字符串转换不允许latin1编码。

I'm using a Latin1 encoded DB and can't change it to UTF-8 meaning that I run into issues with certain application data. I'm using Tesseract to OCR a document (tesseract encodes in UTF-8) and tried to use iconv-lite; however, it creates a buffer and to convert that buffer into a string. But again, buffer to string conversion does not allow "latin1" encoding.

我已经读了一堆问题/答案;然而，我所得到的只是设置客户端编码和类似的东西。

I've read a bunch of questions/answers; however, all I get is setting client encoding and stuff like that.

任何想法？

推荐答案

我已经找到一种将任何编码的文本文件转换为UTF8的方法

I've found a way to convert any encoded text file, to UTF8

var 
  fs = require('fs'),
  charsetDetector = require('node-icu-charset-detector'),
  iconvlite = require('iconv-lite');

/* Having different encodings
 * on text files in a git repo
 * but need to serve always on 
 * standard 'utf-8'
 */
function getFileContentsInUTF8(file_path) {
  var content = fs.readFileSync(file_path);
  var original_charset = charsetDetector.detectCharset(content);
  var jsString = iconvlite.decode(content, original_charset.toString());
  return jsString;
}

我也在这里提到： https://gist.github.com/jacargentina/be454c13fa19003cf9f48175e82304d5

也许你可以尝试这个，其中内容应该是你的数据库缓冲区数据（在latin1编码中）

Maybe you can try this, where content should be your database buffer data (in latin1 encoding)
