Details:

'expand' doesn't replace tab characters by the correct number of spaces in
case the input data contains multibyte characters, e.g. german umlauts when
using the locale UTF-8.

A small example test file is attached.

I've attached a patch to coreutils 8.4 which works for me, but I'm not
experienced in wide character programming, so there might still be some
problem - more tests and review needed.

Thanks for the work, best regards

Herbert.
