Michael,
I think the issue is that there is no Unicode in the script that was attached -
it's just a simple polar call so the user isn't really Unicode".
I think Unicode is starting to creep into the source in various places - we
just had a user point out that negative numbers are using a normal negative
sign ('-1.2') anymore but some kind of Unicode dash that's a lot bigger than
the normal one. I wonder if this could be related...
(If it matters, most of our users would rather have just the regular negative
sign and not embedded Unicode in the axis labels - it looks wrong to them and
makes doing any kind of processing of axis labels more difficult).
