works out A-OK on my Mac. In both Safari and Mozilla. (I don't have IE installed, so I can't test that.)

I see your Greek/Cyrillic/Hebrew characters just fine on both IE and firefox browsers. The problem I seem to have is in copying such characters from some other sites and then pasting them into AWAD's editor -- then I get little rectangles.

for example:
[I can't come up with an example right now; I suppose it is a combination of browser/computer dependency]

here's an example which copies somewhat bizarrely, but note what happened to the expression "'byzantinisation' of σ[sigma] into C".

παρελθοντολαγνεία

I give a similar intrerpretation to the 'byzantinisation' of σ into ϲ


then there is the strange way that OED etymologies copy:
{kappa}{omicron}{rho}{omega}{nu}{giacu}{fsigma}
but I suppose this is an improvement on the ϲs I used to get.

hmmm, the same block of Greek letters comes across as nothing via IE.

There is no straighforward way to get Greek characters in HTML.
