I don't have enough context to see.  raw() doesn't affect echoing.  Assuming
that you have echoing enabled (or are printing to the screen), an accented E
sounds as if the locale is set for Latin-1 (your environment variables
for LC_ALL, etc), which is normally the case with Redhat.  That affects the
behavior of a program which checks if a character is printable, etc.
