I met a very strange problem recently, that is
when I set the following options:
set encoding=utf-8
set ignorecase
then the expression: if "\xe4"=="\xe4" fails.
I test it using:
if "\xe4"=="\xe4"
echo "test"
endif
but I got nothing output, why ?
Try
set encoding=utf-8
if "\xe4" == "\xe4"
redraw!
echo "equal!"
else
redraw!
echo "not equal"
endif
Looks like your message is doing an unwanted disappearing act.

It's not as simple as that, Dr. Chip: I get 0 (zero) as reply to
:echo ("\xe4" == "\xe4")
when 'encoding' is UTF-8. However, the byte 0xE4 by itself is not a
valid character in UTF-8. I also get 1 (one) in reply to
:echo ("ä" == "\xc3\xa4")
where ä (a-umlaut) is Unicode codepoint U+00E4, represented in UTF-8
by the two bytes 0xC3 0xA4.
That's peculiar; I get (when I source the script):
equal!
1
with the following emendation to the script:
set encoding=utf-8
if "\xe4" == "\xe4"
redraw!
echo "equal!"
else
redraw!
echo "not equal"
endif
echo ("\xe4" == "\xe4")
But, without those redraws, I get no message.
