Use oct instead of eval.
Use Encode's encode to find the UTF-8 encoding. 

use Encode qw( encode );

my $unicode_codepoint_hex_lit = '0x20ac';
my $unicode_codepoint_integer = oct( $unicode_codepoint_hex_lit );
my $unicode_char              = chr( $unicode_codepoint_integer );
my $utf8_bytes                = encode( 'UTF-8', $unicode_char );
my @utf8_bytes                = map ord, $utf8_bytes =~ /./sg;
my @nohi_bytes                = map $_ & 0x7F, @utf8_bytes;

print(join(' ', map sprintf('%02X', $_),         @utf8_bytes), "\n");
print(join(' ', map sprintf('0x%02X', $_),       @utf8_bytes), "\n");
print(join(' ', map unpack('B8', pack('C', $_)), @utf8_bytes), "\n");
print("\n");
print(join(' ', map sprintf('%02X', $_),         @nohi_bytes), "\n");
print(join(' ', map sprintf('0x%02X', $_),       @nohi_bytes), "\n");
print(join(' ', map unpack('B8', pack('C', $_)), @nohi_bytes), "\n");
