Fullstop too close with charter

Fullstop too close with charter

[Aditya Mahajan]

Is there a problem with font metrics for charter?

\definetypeface [mainface][rm][serif][charter][default]
                 [encoding=texnansi]
\setupbodyfont[mainface, 10pt]
\starttext
POMDP. Test
\stoptext

The dot is a bit too close to the P, almost touching the vertical 
line. Is there an easy way to correct this?

this is indeed a very annoying property of these font metrics (there are 
more such weird kern pairs), you can edit the afm files and regenerate 
the texnansi metrics

The easy way is to break the pair and then type e.g.:
POMDP\kern -0.1pt.

...or whatever distance suits your eye.  You will need to test the 
distance. The number of these occurrences should be small.  A 
slightly harder way as to define a macro for each combination that 
troubles you. Or you can do what Hans suggests below as a more 
general solution.  But I would test the distances first.

Thank You. For the time being I have done manual correction since I 
have to finish the whole thing by tomorrow.  I will explore modifying 
afm files when I have a bit more time.

Thanks,
Aditya
