I think last time I looked into this there was no normalization of
package.conf data; if it was read in in a particular encoding, it was
stored in that encoding and you can get an exception trying to dump it in a
different encoding.  Certainly I have found ISO8859-1 encoded text in my
package.conf.d/* files, when I would expect (and was configured for) UTF-8.
 This also suggests that ISO8859-1 text in a *.cabal file would remain
ISO8859-1 in the resulting package.conf file even if UTF-8 encoding was
active at the time.
