Always getting binary diffs, even for html pages about sitediff HOT 5 OPEN

Hello, I think I have a possible source of the problem.
First I will put you in context:

I was trying to compare 2 web pages ( using NGINX ), the web pages and sitediff inside a docker container.

Both websites had the default content, except for a small change to check and review the differences between the two.
Sitediff detected that there were the changes but only showed the difference between binary and as everyone I am interested to view the differences.

In my case specific to both NGINX servers (containers) the charset was not specified and defining it in the index.html file did not work.

The solution

The solution in my case is to define the charset in the Nginx configuration file /etc/nginx/nginx.conf the charset inside the http or https block:

. . .
http {
    charset       utf-8;
     . . .
}

After the changes you would only have to reload nginx:

 $ /etc/init.d/nginx reload

So be careful with the configuration of your web service.

It's hard for me to verify, but I'd start by looking at the headers returned by your http servers. Might be that you can resolve by setting an appropriate header.

I haven't looked at this issue personally, but let's keep this open for now pending further testing.

I've seen this one before. I think this happens when the library that reads a URL as HTML cannot determine the encoding for the page. That's when the Result class (if I remember correctly) treats the content as binary and compares hashes instead of actual content.

I get this with the default/initial (example?) HTML files, but not with my own site's HTML files.

Ubuntu 18.04, installed via Docker (1.0.0 and latest).

If SiteDiff can't determine the character encoding of the files, it will revert to a "Binary" encoding. This is something we wish to improve.
