That's called kerning.  You can determine how much kerning is applied to
a pair; I posted at length on this subject deep in a thread over in 
povray.programming.  I even wrote a couple macros.

// Find the advance width of character C in font F
#macro WidthWithSpacing( C, F )
  #local T=text {ttf F concat("|",C,"|") 1 0}
  #local W1=max_extent(T).x-min_extent(T).x;
  #local T=text {ttf F "||" 1 0}
  (W1-max_extent(T).x+min_extent(T).x)
#end

// Find the width of the glyph for character C in font F
#macro WidthNoSpacing( C, F )
  #local T=text {ttf F C 1 0}
  (max_extent(T).x-min_extent(T).x)
#end

// Find the kern for characters A and B from font F
#macro Kern( A, B, F )
  (WidthWithSpacing( concat(A, B), F)-WidthWithSpacing(A,F)
   -WidthWithSpacing(B,F))
#end
