Hi Steffen,
data aren't that easy. There are non-latin1-characters encoded in the UTF8 part. I expect
among others typographic apostrophes, polish characters, some mediaevalist characters like
ũ (u with tilde). Maybe, there is also some greek inside, but I am not sure about that.

Isn't a shell script with a truly validating iconv(1) enough?
This works for me if in utf8.1 there is 'ÄEIÖÜ' in UTF-8 and i run

?0[steffen@sherwood tmp]$ iconv -f latin1 -t utf8 < utf8.1 > utf8.2

As in

for i in utf8.1 utf8.2; do
if iconv -f utf8 -t latin1 < ${i} |
iconv -f utf8 -t utf8 >/dev/null 2>&1; then
echo ${i}: bummer, going home by one
iconv -f utf8 -t latin1 < ${i} > ${i}.new 2>&1
echo ${i}: valid UTF-8

i'll end up as

?0[steffen@sherwood tmp]$ sh
utf8.1: valid UTF-8
utf8.2: bummer, going home by one
?0[steffen@sherwood tmp]$
