yes agreed although rather than inputenc try to guess that the font 
encoding isn't going to work it would probably be better if fontenc
warned if it was on xe/latex with utf8 input encoding that it can't load 
unicode fonts. because on xelatex you'd get exactly the same problems if 
you did

     %\usepackage[utf8]{inputenc}
     \usepackage[T1]{fontenc}
     \usepackage{textcomp}


and changing the messages in inputenc would not help that:-)


I just changed inputenc (again) in svn to give different messages in the 
ascii and utf8 cases (still letting (x-)ascii and utf8(x) through with 
just a warning).
