This is not strange, tr is somewhat like tolower/toupper (as opposed
to towlower/towupper):

% echo 'abcабц' | iconv -t CP1251 > /tmp/enctest2
% cat /tmp/enctest2 | LANG=ru_RU.CP1251 tr '[:lower:]' '[:upper:]'
| iconv -f CP1251
ABCАБЦ
% cat /tmp/enctest2 | iconv -f CP1251 | tr '[:lower:]' '[:upper:]'
ABCабц

: it works only with single bytes. Each of the characters "čšž" in
UTF-8 occupies more then one byte, thus you need to use CP1250 locale
for this to work.

Cannot find this in `man tr` though, but `info tr` has
