[Inkscape-user] A problem with Greek letters

I have recently moved my work from an old laptop to my new one. On my new laptop, Inkscape (which is likely a slightly newer version than that on my old laptop) is not correctly rendering any of the Greek letters in my figures. A sigma is shown as an 's', etc.

All letters were composed in verdana using copy/paste from character map in Windows XP. They have transferred to two other computers correctly (and obviously show up correctly on the old laptop). I can compose NEW Greek letters via this method on these SVG's perfectly. I am using Version .45.1. Other special figures, like the bullet and the infinity symbol, rendered fine.

Any ideas?

I searched the forum for the keywords "Greek letters" but I found nothing useful.
