Hello,

I found some useful stuff at:
http://www.tcl.tk/man/tcl8.4/TkCmd/canvas.htm(Find "-fontmap" there)

The above document recommends a notation like: *
-*-Courier-Bold-R-Normal--*-120-

*I think this notation will be like this for those fonts that have spaces:

*"-*-DejaVu Serif Condensed-Bold-R-Normal--*-120-*"
