thanks for explaining this

unfortunately this doesn't work with the html or plain-text help (i 
assume it does work with the PDF manuals). in the html/plain text help, 
it always puts the plain ascii 'omega', rather than the actual symbol.

so it's seeming like it's not possible to have special chars in the html 
or plain-text help, without upsetting the winbuilder?

if i have to use the plain ascii 'omega', 'eta', 'alpha', it won't be 
the end of the world.

with thanks
