That problem has been discussed several times on the coot mailing list.
Currently a workaround is to type:
(set-use-stroke-characters 1)
in scheme console (Calculate > Scripting > Scheme).
(You can also add it to coot settings).
As a side effect fonts will look worse.
I've just tested a better fix (patch attached) and it seems to work,
It requires compilation from source, so for now use the workaround
above.
