[JW Lua] FCShapeDefInstructions:AddDrawChar uses signed unicode value, instead of unsigned

[Jan Angermüller]

It does, but AFAIK only through Shape Def library import as the Shape 
Def dialog has no copy/paste for unicode symbols.
But these shape def libraries work fine, so internally unicode shape are 
working fine.

I tried to change my code that automatically writes a shape def library 
with ascii or unicode to automatic shape creation within Finale and 
there I noticed the behaviour. The reading/writing of the unicode shape 
def library works fine. It's only the AddDrawChar() that doesn't work 
internally.
