I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in its classical Greek synthetic form and in its more modern analytical/transformational form.

comment Can't plot rotated region
@user21. re: "an expr with Head TransformedRegion does not work." I don't think that is the issue since TransformedRegion[Rectangle[], RotationTransform[45 °, {.5, .5}]] has head TransformedRegion, but can be plotted by RegionPlot.

comment Webdings are different on V10 vs V9. Why?
You're right, I can't explain why. Perhaps you should ask WRI on Wolfram Community.

I thought your question was about how things work in V10.

comment Webdings are different on V10 vs V9. Why?
Yes, you can't access Webdings in V10. Style or something it calls must have changed. The option FontFamily no longer has any effect for that font in Style. I seem to recall that there is "better" integration of Unicode in V10. I suspect that may at the root.

Because of what I need to do to access ZapfDingbats in V10. See my answer.

I'm running on OS X and it appears that a needed file /Applications/Mathematica.10.app/SystemFiles/CharacterEncodings/Webdings.m is not installed in V10.
