It is thus not possible to specify an Xft default font. Each application would have to be configured separately. The solution IMO is to indroduce new variables for the new font specifications, just like xterm did when it gained Xft support (XTerm*faceName, XTerm*faceSize). A big difference between Tk and xterm is that in Tk you can't choose between font rendering systems at runtime as in xterm (-fn or -fa in command line, font or faceName and faceSize in XRDB). Tk can be compiled with Xft support in which case it renders all fonts using Xft. So, if Tk is built with Xft enabled, it still understands XLFD but converts it into Xft structure internally. As a result, you don't have to use the new font naming format in your resource file. Just specify XLFD and Tk will still use Xft to render fonts. For DejaVu Sans Mono 7 the following specification should be acceptable by both emacs and Tk: *font: -dejavu-dejavu sans mono-medium-r-normal-*-*-70-*-*-*-*-*-* If you want to specify different fonts based on toolkit they are based on, then you're out of luck, because XRDB doesn't allow that. I'm changing the bug severity to wishlist as it doesn't fit to important, and will close it if yuo won't give some more info.
