This works as you say it should for me, in gnome-terminal and kgx
(gnome-console).

What byte sequence is output from iconv on your system?
(echo -e "e\xcc\x81e" | iconv -f utf-8 | xxd)

I expect that the answer should be:

00000000: 65cc 8165 0a                             e..e.

which is U+0065 'e', U+0301 combining acute accent, U+0065 'e', newline.

I have version 1.55.0+ds-3, if that matters.

I have version 0.78.2-1, if that matters.
