Sorry for the late reply, I wrote this a while ago, but left the draft
to get a friend's oppinion on the first bit.

The question refers to the bit quoted from the website, not the bit
that is quoted here at the top. Without proper context (that it is
referring to 'data-encoding') that passage is hard to decipher. Not
finding sense in the paragraph's first sentence, I focused harder on
it rather than read around it. Fortunately, I was shown the error of
my ways and things are finally clearing up.

OK, now we're cooking. So, the de.dat declares the word list files to
be in iso-8859-1 and this should direct aspell to treat them as such.

Tried both LC_ALL="C" and "POSIX" but no go. Should I try to generate
an ISO 8859-1 character encodings and try with it set? Do you have any
other suggestions?

:-) Nevermind. Stems from confusion about that paragraph in the users
