Hi, I am having an interesting problem when setting "(f" using XeTeX and
the Adobe Kepler Std fonts: in the resultant PDF, there is a space in
the middle, such that the output looks like "( f" instead. I have
placed an example of the output on my website, showing several times
when the problem occurs:
In a PDF reader that allows character-wise selection (e.g. Evince) you
can select the space between the parenthesis and the f. Here is the
source of that PDF above, which I compiled simply with "xetex <file>":
\font\kepler="Kepler Std:+liga" \kepler Regular, Ligatures: (f) (fi)\par
\font\kepler="Kepler Std:-liga" \kepler Regular, No Ligatures: (f) (fi)\par
\font\kepler="Kepler Std Bold:+liga" \kepler Regular Bold, Ligatures: (f) (fi)\par
\font\kepler="Kepler Std Bold:-liga" \kepler Regular Bold, No Ligatures: (f) (fi)\par
\font\kepler="Kepler Std Italic:+liga" \kepler Regular Italic, Ligatures: (f) (fi)\par
\font\kepler="Kepler Std Italic:-liga" \kepler Regular Italic, No Ligatures: (f) (fi)\par
\font\kepler="Kepler Std:+smcp" \kepler Regular Small Caps: (f) (fi)\par
\font\kepler="Kepler Std Caption:+liga" \kepler Caption: (f) (fi)\par
\font\kepler="Kepler Std Subhead:+liga" \kepler Subhead: (f) (fi)\par
\font\kepler="Kepler Std Display:+liga" \kepler Display: (f) (fi)\par
All instances of "(f" show up in the output as "( f" with the exception
of the small capitals. With the fi ligature, there is a visible space
equivalent in size to that before the standalone f, but the space isn't
selectable in Evince like it is before standalone f.

There are newer versions according to the Kepler readme file at:
But none of the changes listed since 2.020 seem significant to this
problem. I note that this problem does not occur with any other fonts,
nor any other combination of characters that I've found. This seems
like a very strange problem, thanks in advance for any ideas on how to
