Thanks for your reply, Hans.

Sorry, my question was inaccurate.

I know that kerning information is in the font, but it is ConTeXt that
uses this information (or not).

As far as I know, there are two kinds of kerningns: an OT kern feature
from the GPOS table and an old TrueType 'kern' table.

In the following sample OpenType features aren't enabled:

\usemodule[simplefonts][size=30pt]
\setmainfont[FreeSerif]
\starttext
dadedidodufafefifofufrflftlalelilolutatetitotu\par
{\em dadedidodufafefifofufrflftlalelilolutatetitotu\par}
{\bf dadedidodufafefifofufrflftlalelilolutatetitotu\par}
{\bf\em dadedidodufafefifofufrflftlalelilolutatetitotu\par}
\stoptext

I'm using TrueType fonts of FreeSerif. Isn't the TrueType 'kern' enabled
by default in ConTeXt? (The glyphs in the example above have no kerning
at all, so I wonder whether at least the TrueType 'kern' table should be
used by ConTeXt.)

Many thanks for your help,


Pablo
