It sounds like this is more of a problem with LinkCad than anything
else. You might want to try a different route.

If you really need to do that though, maybe try a font like Deplof.
You can get it from the WieWeb website. I use it because it's designed
to prevent small, normally disconnected font parts (like the circle in
an "O") from flying off during development / etching but they also
claim it reduces file sizes. It's free too.

Go to:
http://www.wieweb.com/
then click on "Downloads" (their site has these java frames in it, so
a direct link doesn't seem to work well).
