Charset problem

[romuloinnocencio]

I'm having problems with charset, naturally the codes in .aspx need (and I don't know ecxacly why) the ISO-8859-1. Prints someting like this: *capacita��o de *

        browserSync: {
            geral: {
                bsFiles: {
                    src: [
                        '**/*.html',
                        '**/*.css',
                        '**/*.min.js',
                        '**/*.aspx',
                        '**/*.master',
                        '**/*.ashx'
                    ]
                },
                options: {
                    watchTask: true,
                    startPath: "/default.aspx",
                    proxy: config.host + ':' + config.port,
                    notify: false,
                    open: false
                }
            }
        },

With aspx, ours programmers insert the content of news, in web.config I found this.

But if i change the value of charset here, nothing more works.

Same problem here, we are also stuck with ISO-8859-1.

None of matter with you but http://prnt.sc/ is too slow... Just pasting the image to the Github issue comment is easier and more useful. https://help.github.com/articles/issue-attachments/

I'm trying to nail this down, so far the problem is confirmed to be upstream, related to the foxy proxy, and there is even an open issue regarding encoding problems:

Here's a small gist for testing:

Any solution? I am using iso-8859-1 unfortunately I can not change the application Chasert it causes problems in other services.

Similar problem when using proxy mode of BrowserSync.

Application on the background is made with Java, and sadly can't change the existing content encoding settings from there.

Now text displays like:

Without proxy (and without BrowserSync...), it looks like:

please fix this one

I'm having this problem too. Any fix available?

@shakyShane Please fix!

[bunam]

me too 👅

Any news or workaround on this problem?

Based on @kokarn's and @youngzhaosignifyd's examples and with the help of iconv-lite, plus using proxyRes option I am successfully using this script:

proxyRes: [
  (proxyRes, req, res) => {
    if( proxyRes.headers && proxyRes.headers["content-type"] &&
        proxyRes.headers["content-type"].match("text/html") ) {
            
      const _end = res.end
      const _writeHead = res.writeHead
      let writeHeadArgs
      let buffer = new Buffer("")

      proxyRes.on("data", (chunk) => {
        buffer = Buffer.concat([buffer, chunk])
      })

      res.write = () => {};
      res.writeHead = (...args) => {writeHeadArgs = args}

      res.end = () => {
        _writeHead.apply(res, writeHeadArgs)
        _end.call(res, iconv.decode(buffer, "iso-8859-2"))
      }
    }
  }
]

My solution, strongly based on @skotniczny solution. I had to set a content-type header, because my backend insisted on the broken encoding.
You have to have iconv-lite and browser-sync installed.
Note: We have windows-1252 encoding in the backend.

var browserSync = require("browser-sync").create();
var iconv = require("iconv-lite");

/**
 * This example will serve files from the './app' directory
 * and will automatically watch for html/css/js changes
 */
browserSync.init({
  watch: false,
  proxy: {
    target: "http://localhost/WorkServer/admin",
    proxyRes: [
      (proxyRes, req, res) => {
        if (
          proxyRes.headers &&
          proxyRes.headers["content-type"] &&
          proxyRes.headers["content-type"].match("text/html")
        ) {
          const _end = res.end;
          const _writeHead = res.writeHead;
          let writeHeadArgs;
          let buffer = new Buffer("");

          proxyRes.on("data", chunk => {
            buffer = Buffer.concat([buffer, chunk]);
          });

          res.write = () => {};
          res.writeHead = (...args) => {
            writeHeadArgs = args;
          };

          res.end = () => {
            _writeHead.apply(res, writeHeadArgs);
            _end.call(res, iconv.decode(buffer, "win1252"));
          };
        }
      },
      function(res) {
        if (
          res.headers &&
          res.headers["content-type"] &&
          res.headers["content-type"].match("text/html")
        )
        res.headers["content-type"] = "text/html; charset=utf-8";
      }
    ]
  }
});

I'm trying to use the code above but I'm getting the following error:

node:_http_server:279
    throw new ERR_HTTP_INVALID_STATUS_CODE(originalStatusCode);
    ^

RangeError [ERR_HTTP_INVALID_STATUS_CODE]: Invalid status code: undefined

Any idea what could be missing in my case?

Fixed version. Tested node v17.9.0.

var browserSync = require("browser-sync").create();
var iconv = require("iconv-lite");

browserSync.init({
  watch: false,
  proxy: {
    target: "http://mydomain.local",
    proxyRes: [
      (proxyRes, req, res) => {
        if (
          proxyRes.headers &&
          proxyRes.headers["content-type"] &&
          proxyRes.headers["content-type"].match("text/html")
        ) {
          const _end = res.end;
          const _writeHead = res.writeHead;
          let buffer = Buffer.from("");

          proxyRes.on("data", chunk => {
            buffer = Buffer.concat([buffer, chunk]);
          });

          res.write = () => {};
          res.writeHead = (...args) => {
            _writeHead.apply(res, args);
          };

          res.end = () => {
            _end.call(res, iconv.decode(buffer, "iso-8859-1"));
          };
        }
      },
      function(res) {
        if (
          res.headers &&
          res.headers["content-type"] &&
          res.headers["content-type"].match("text/html")
        )
        res.headers["content-type"] = "text/html; charset=utf-8";
      }
    ]
  }
});
