Completely rewrite the scramble() and unscramble() functions

The file output is now completely in ASCII---and will be much harder to
break for casual cheating!

Minor clean-up: replace character constants with wide-char versions
...
Wide-char character constants is not strictly needed for most (all?)
modern C compilers, as ASCII maps to wchar_t directly (as long as
__STDC_ISO_10646__ is defined). However, it doesn't hurt to be pedantic!

Add the functions xwcrtomb() and xmbstowcs()

The xwcrtomb() and xmbstowcs() functions replace illegal characters with
EILSEQ_REPL ('?'). Adjust other functions, particularly mkchstr() and
friends, to suit.
