  \C  Match a single C char (octet) even under Unicode.
               NOTE: breaks up characters into their UTF-8 bytes,
               so you may end up with malformed pieces of UTF-8.
               Unsupported in lookbehind.

# perl -e 'use utf8;  binmode(STDOUT, ":utf8"); $s="\x{0110}";  $s =~
m/(\C)(\C*)/;  print "$s: 1=",length($1)," 2=",length($2),"\n"'
Đ: 1=1 2=1

I argue that it's not a non-sense, but only for experts .
