This works​:
rakudo$ ./perl6 -e '"\c[LATIN CAPITAL LETTER D,COMBINING DOT BELOW,COMBINING DOT ABOVE,COMBINING HORN]";'

My versions​:
rakudo$ ./perl6 -v
This is Rakudo Perl 6, revision 37980 built on parrot 1.0.0-devel
for i486-linux-gnu-thread-multi

rakudo$ icu-config --unicode-version
5.1

In comparison the following Perl 8.10 script does not croak​:

use strict;
use warnings;

use charnames qw(​:full);

my $s= "\N{LATIN SMALL LETTER A WITH DIAERESIS}\N{COMBINING CEDILLA}";

use Encode;
decode("utf8",encode("utf8",$s,1),1);

Added as a test to t/spec/S02-literals/char-by-name.t - thanks for the
report.

The test passes now, so I'm marking this resolved.
