Yes. To find the number of bytes text would take encoded as UTF-8, encode it using UTF-8, then use length. 
use charnames qw( :full );
use feature qw( say );
use Encode qw( encode_utf8 );

my $text = "\N{LATIN SMALL LETTER E WITH ACUTE}";
say length $text;  # 1

my $utf8 = encode_utf8($text);
say length $utf8;  # 2
