I'll post an update of both the PDF file and the font itself later
tonight. The PDF file that is there now requires Reader > 3.0.

I would prefer something a little bit more specific. There are so many
possible symmetry cases that we might end up with a full font that
contains only harpoons...
Lots of the "missing cases" are already in the STIX tables for
precisely this reason, but there is just not enough room to capture
all possible cases.

This one, for example, is already available (121). But there is no
negated version of the left-pointing version while there is a negated
version of the "leadsto" (123).
Please have a look at the PDF file tomorrow (I'll post one that works
with Reader 2.1).
