Hello
I can't add anything on the technicalities involved in tweaking the kerning
of fonts, but in a couple of previous threads I've asked if it might be
possible to add a user-generated kern option (which would adjust and
supplement rather than completely overwrite the kerning information in the
font). This (I understand) is possible in LuaTeX but I think the response
was that XeTeX looks at the font information at a different point in the
processing from LuaTeX, and it would be very difficult to feed in tweaks and
adjustments after that point. What I was hoping for was to load a font with
something like "kerning=mykerns", just like "mapping=tex-text". The user
would then compile (to a predefined format) a file such as mykerns.krn,
which would then feed the required information to XeTeX.
As things stand, I don't *think* it's legal to adjust the kerning in
commercially supplied fonts (even those that may ship free with a product
supplied by a firm such as Adobe). But I'm no expert on the legalities
(common sense would suggest that they should be glad of improvements
introduced by users, but this may not be an area where common sense
matters).
Best
John

Thank you, Peter. I tried but it's still far from being satisfying. Too
much on the right now. Looking on FontForge the kerning set by designers
for the combination of glyphs uni0423+uni0431.ital is -53. Previously
Peter reported a kerning value of -183. However, I don't know if the
units of measurement were the same, though.
