Font Editor for a Conscript

[rr]

I made a font using my language's script, but this is the best I could come up with.

The problem is, my conpeople write using a stylus, so none of these symbols, except for maybe one of them, are accurate.
I made this font using FontStruct, but it's not very good for curved lines and is quite limiting. I tried using FontForge, and that crashed on my computer.

Is there a free font editor that supports curved lines, preferably a program that uses vector graphics instead of bitmap?

You may want to try Inkscape for a free vector graphics program. Fontforge – although it currently crashes on you – is probably still the best free font editor, however, I have no experience of using Fontforge under Windows (I assume you use that as your OS). Since it's a Linux program, I suppose it's best run under that (it runs nicely on my Ubuntu installation), or you try getting it to run under Cygwin – at last that worked for me back when I still ran Windows. It may require some fiddling around, but there's probably walkthroughs on the internet.
