Not sure if my comment is valuable here, but I had a similar issue that I want to share with you, who knows may be it can help some of you.

For my project, I have activated the GZIP in my CI config file:

$config['compress_output'] = TRUE;

In the config file it is well said that:

| Enables Gzip output compression for faster page loads.  When enabled,
| the output class will test whether your server supports Gzip.
| Even if it does, however, not all browsers support compression
| so enable only if you are reasonably sure your visitors can handle it.
|
| VERY IMPORTANT:  If you are getting a blank page when compression is enabled it
| means you are prematurely outputting something to your browser. It could
| even be a line of whitespace at the end of one of your scripts.  For
| compression to work, nothing can be sent before the output buffer is called
| by the output class.  Do not 'echo' any values with compression enabled.
|
*/

The "Do not 'echo' any values with compression enabled." is very important here.

However, my function needs to echo a json encoded array for my Ajax call.

In order to fix that, I have added the "exit" function after my "echo" into the function.

    echo json_encode($arr_ajaxResults);
    exit();

Now, with this input, I don't face no more the "Content Encoding" error.

I hope it can help guys who have the same issue.
