I haveurxvt.font: xft:Deja Vu Sans Mono:size=10emacs.font: DejaVu Sans Mono-10in my .Xresources.  Does this mean different versions of thefont are used?  In the urxvt (or xft?) version there are severalerrors in 'polytonic' Greek letters.  E.g., GREEK SMALL LETTERUPSILON WITH PERISPOMENI shows up as GREEK SMALL LETTER UPSILONWITH MACRON.  Can something be done about this?In fact, the same error occurs with the default font.PS.I have now found the error is due to something calledanti-aliasing, a method of smoothing fonts.  It can be eliminatedby adding :antialias=false to the font selection, but thisyields a jagged rendering.It would be nice if there were a better solution.
