Try C-u C-x = on any character.  It will display relevant information on
the character at point.  This should look like this:

========================================================================
        character: ! (33, #o41, #x21)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x21
           syntax: .    which means: punctuation
         category: a:ASCII graphic characters 32-126 (ISO646 IRV:1983[4/0]) 
l:Latin r:Japanese roman
      buffer code: #x21
        file code: not encodable by coding system utf-8
          display: by this font (glyph code)
     dejavu sans 
mono:pixelsize=12:foundry=unknown:weight=medium:slant=r:width=normal (#x04)

Character code properties are not shown: customize what to show

There are text properties here:
  auto-composed        t
  face                 myblack
  gnus-face            t
  gnus-number          4883
  gnus-position        t
========================================================================

In the first part, you find information on font and face.  

Here the font is:

     dejavu sans 
mono:pixelsize=12:foundry=unknown:weight=medium:slant=r:width=normal (#x04)

The face is defined by special text properties.  See the second part -
here, there are two special text properties that are relevant to Emacs
face rendering :

  face                 myblack
  gnus-face            t

More on faces :
