Sorry for the delay in response, but there have been distractions, I had trouble finding the code, and then dithered over whether to just put it somewhere public and point to it (I decided not to).

Assuming $in has been properly decoded, I was proposing something like the following:

use Unicode::Normalize qw{ NFKD };
...
my $out = NFKD( $in );
$out =~ s/ \p{NonspacingMark}+ //smxg;

Note that this does not handle anything but diacritics. The above will change 'Köln' to 'Koln', but 'Øslo' (if it were really spelled that way) remains 'Øslo', because Unicode does not consider the stroke to be a diacritic.

I think that for comparing things Unicode::Collate is actually the way to go
