For hunspell dictionaries, the .aff files contain the encoding for
the .dic files, the .aff needs to be changed to specify UTF-8 if you
change the encoding of the .dic files. This tool though looks like its
for validating thesaurus files, though they probably have the same thing
where there's a field somewhere to indicate the encoding they are in.

Some of the hunspell dicts might share ispell lineage I guess, but
either way most of them and the thesauri have their own active upstreams
and so on, so yeah, changing the encoding just add unnecessary diversity
from their upstreams.

anyway, the last patch looks pretty minimal and it seems to make no
difference to the "typical" setup, so I pushed that now to dictionaries
