Hi Paul,
I suppose that screen readers can gather the text only if font
rendering is done by operating system facilities which provide a hook
for them.

If a program is using its own font rendering library, I suppose that
there is no such hook, i.e. the text is only visible to the program
itself, which then creates bitmaps of the glyphs in order to display
them on screen.

I fear that most free programs are using free libraries like freetype
but screen readers on Windows hook into libraries provided by Microsoft.

Regards,
  Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
