I was able to hit on a solution to the first question with some help from Google.
This test code works well, although I confess that I don't fully yet understand the codepoint_hex method that gets me the code point I need:
while($testStr =~ m/(.)/g) {
$string = pad(codepoint_hex($1));
print("$string\n");
print charnames::viacode($string) . "\n";
}
sub codepoint_hex {
if (my $char = shift) {
return sprintf '%2.2x', unpack('U0U*', $char);
}
}
sub pad {
my $str = shift;
while (length $str < 4) {
$str = "0$str";
}
return "0x$str";
}
Result:
0x03bb
GREEK SMALL LETTER LAMDA
0x03b1
GREEK SMALL LETTER ALPHA
0x1f78
GREEK SMALL LETTER OMICRON WITH VARIA
0x03c2
GREEK SMALL LETTER FINAL SIGMA
