Due to a bug in some older versions of PHP the check for method_exists('Normalizer', 'normalize') fails. We better work around by adding a check for class_exists('Normalizer') first.
Reported and discussed in the forum.
See also the related report. The best solution seems to check for class_exists('Normalizer', false).
class_exists('Normalizer', false)
Fixed with r1682.
