You can use the 'original' abbreviations if you feel more comfortable:

<?php
Normalizer::NFD;
Normalizer::NFKD;
Normalizer::NFC;
Normalizer::NFKC;
?>

"If you get error messages while starting apache of xampp package with activated extension=intl.dll," do NOT copy any files around.

Use Apache's "LoadFile …" functionality to load any missing DLL's not found within a %PATH%. Even php##ts.dll itself.
