Trying to match full utf-8 characters, eg, get the following to output ab with ellipsis (e280a6) removed: 
echo -n 'a…b' | perl -pe 's@(.).(.)@$1$2@';

Instead of only removing the first unicode point. I have been reading https://perldoc.perl.org/utf8.html and https://perldoc.perl.org/Encode.html, but can't seem to find a combination that works. I've tried: 
echo -n 'a…b' | perl -pe 'use utf8; s@(.).(.)@$1$2@';
echo -n 'a…b' | perl -pe 'utf8::encode($_); s@(.).(.)@$1$2@';
echo -n 'a…b' | perl -pe 'utf8::upgrade($_); s@(.).(.)@$1$2@';
echo -n 'a…b' | perl -pe 'use Encode qw(decode encode); $_ = encode("u
+tf-8", $_); s@(.).(.)@$1$2@';
echo -n 'a…b' | perl -pe 'use Encode qw(decode encode); $_ = encode("u
+tf8", $_); s@(.).(.)@$1$2@';

The only thing I've found so far that works is this, but is deprecated :-/ (and I believe applies to the whole script): 
echo -n 'a…b' | perl -pe 'use encoding 'utf8', Filter => 1; s@(.).(.)@
+$1$2@';
