Object Type Path to UseFontSubstitution


With the UseFontSubstitution property enabled, RichEditControl selects the characters among the fonts available in a font cache.

The substitution font should meet the following requirements.

  • It contains a symbol mapped to the missing character.
  • Its PANOSE distance (i.e., a measure of visual difference) is minimal.

The following image illustrates the UseFontSubstitution property in action.


In the image above, the font has been changed from Arial to Arial Black. Since the Arial Black font has no symbol for representing the Object Replacement Character, the control substitutes this character by using the Arial font (shown in the image below).
