Description
There are more ways how to save UTF-8 strings. This means that when one want to compare two strings it can be not that simple and intuitive.
$char_A_ring = "\xC3\x85"; // Å 'LATIN CAPITAL LETTER A WITH RING ABOVE' (U+00C5)
$char_combining_ring_above = "A\xCC\x8A"; // Å 'COMBINING RING ABOVE' (U+030A)
assert(\Nette\Utils\Strings::compare($char_A_ring, $char_combining_ring_above)); //error
assert(\Nette\Utils\Strings::normalize($char_A_ring) === \Nette\Utils\Strings::normalize($char_combining_ring_above)); //error
assert($char_A_ring === $char_combining_ring_above); //error
I would expect that when I do this after Strings::normalize() this would succeed, but it does not. I would expect to normalize everything into NFC or NFD (does not matter that much). Currently there is no guarantee that two same strings will be understood as the same.
