That falsely reports lines with tab characters.  This fixes that problem
(at least in shells which accept $'...' syntax)

        LC_ALL=utf8 egrep -n $'[^ -~]' file.tex

(Although my system complains
        warning: setlocale: LC_ALL: cannot change locale (utf8)
so maybe a bit more UTF magic is desired anyway.  Or maybe my system needs
work.)
