I have the same problem with DejaVu: -unknown-DejaVu Sans Mono-normal-normal-normal-*-15-*-*-*-m-0-fontset-a= uto2 which is basically the most popular free font. And yet when I paste a problematic char, like =F0=9D=9D=B9 into gedit, configured also with DejaVu= Sans Mono, there's no issue. So it can be solved, since gedit does it. Oleh
