Dapper xterm charset incompatibility?

[Lee Revell]

I am using a standard xterm to ssh into a box running an OOTB Dapper
install and compiling a kernel.  For some reason the display is
corrupted:

  CC      kernel/power/pm.o
kernel/power/pm.c:241: warning: â is deprecated (declared at kernel/power/pm.c:64)
kernel/power/pm.c:241: warning: â is deprecated (declared at kernel/power/pm.c:64)

                               ^^^
  CC      kernel/power/poweroff.o

What is with the "â"s?  Have we broken backwards compatibility with
xterm?  Do I need to use a Unicode capable xterm to do this?
