Bug in STIX fonts

Grumble, grumble. MathML on Firefox on mac was going great guns, until I find that
\mathcal{N}
gives me garbage (but
\mathcal{M}
looks fine). I see from this bugreport, that this is an issue with the STIX fonts.

Flowing text in inkscape (Poster making)

You can flow text into arbitrary shapes in inkscape. (From a hint here).

You simply create a text box, type your text into it, create a frame with some drawing tool, select both the text box and the frame (click and shift) and then go to text->flow into frame.

UPDATE:
