I am trying to prepare a moderate sized document in Malayalam using
Context. Overall I have been successful. However, there are a few rough
edges for which I need help. This is the fifth problem I face.
Is it possible to instruct Context to use a font in general, except for
a single character? I want to show the space character with open box,␣
U+2423. However, the font doesn't have that character. The open box
character shows up in many places within an otherwise Malayalam text.
So, switching font is not possible. For the time being, I am using a
substitution. However, I would like to know if it is possible.
