Bug 914: Don't let UTF-8 I/O affect internal representations.

Browse Source 
Use it for the actual I/O only.  Previously, defining CONFIG_UTF8 and
enabling UTF-8 used to force many strings to the UTF-8 charset
regardless of the terminal charset option.  Now, those strings always
follow the terminal charset.  This fixes bug 914 which was caused
because _() returned strings in the terminal charset and functions
then assumed they were in UTF-8.  This reduction in the effects of
UTF-8 I/O may also simplify future testing.
