Trying to find what character was replaced with Unicode replacement character
I am working with Firefox 52.1.2 on Ubuntu 14.04 (x86). In general I can see characters correctly, but sometimes I see a Unicode replacement character (octal 357 277 275), for example on this page:
http://www.mathhelp.com/how_to/slope-intercept_form/using_slope-intercept_form_to_graph_a_line/
I see "equation of a line is y = 3/4 x (?) 2" and I suspect from context the replaced character is a dash or minus sign.
I have verified that I enabled the option for pages to download their own fonts.
I'm trying to find out exactly what was the replaced character so that I can try to find a font to install which contains it, but when I copy and paste the text, I get the Unicode replacement character, not the original character. How can I find out what's the original character?
I tried looking at the page source -- no luck, the replacement character appears there too.
Thanks in advance for any advice.

The page appears to be viewed with Western encoding selected and doesn't work properly with Unicode. When I select Western then I see the – = – character instead of the diamond with the question mark: y = 3/4 x – 2
Does this works for you or is there still a problem?

Yes, that fixes the problem! But I wonder why it's necessary to select the encoding. I thought that the web page would tell the browser what encoding to use. Anyway, I'm glad that I know how to fix it now, thanks a lot for your help.
You're welcome.
A diamond usually indicates an encoding issue. If there is a problem with font support then Firefox would show a little box with the hex code of the character.
