not precisely. it certainly *can* commit such messages (I just did so), 
but it gets cranky if you try to commit them from an environment in 
which neither LANG, LC_CTYPE, LC_ALL, or CHARSET are set to the source 
codeset (such as UTF-8).

I'll admit, it's a terrible error message. but it's a legitimate 
conversion failure if you're telling it to read umlauts from, say, 
LANG=C (which implies the input form is ASCII). what does your 
environment look like?

note also that if you're trying to do this from an autotest script, 
autotest takes the liberty of resetting LANG, LC_CTYPE, and LC_ALL 
before running each command, so you're stuck having to use CHARSET for 
autotest scripts.
