NORMALIZER(3)								 1							     NORMALIZER(3)

The Normalizer class

INTRODUCTION
	Normalization  is a process that involves transforming characters and sequences of characters into a formally-defined underlying represen-
       tation. This process is most important when text needs to be compared for sorting and searching, but it is also used when storing  text	to
       ensure that the text is stored in a consistent representation.

	The Unicode Consortium has defined a number of normalization forms reflecting the various needs of applications:

	      oNormalization Form D (NFD) - Canonical Decomposition

	      o Normalization Form C (NFC) - Canonical Decomposition followed by Canonical Composition

	      o Normalization Form KD (NFKD) - Compatibility Decomposition

	      o Normalization Form KC (NFKC) - Compatibility Decomposition followed by Canonical Composition

	The  different forms are defined in terms of a set of transformations on the text, transformations that are expressed by both an algorithm
       and a set of data files.

CLASS SYNOPSIS
       Normalizer

       Normalizer

       Methods

       o publicstatic bool Normalizer::isNormalized (string  $input, [string  $form = Normalizer::FORM_C])

       o publicstatic string Normalizer::normalize (string  $input, [string  $form = Normalizer::FORM_C])

PREDEFINED CONSTANTS
	The following constants define the normalization form used by the normalizer:

	      o Normalizer::FORM_C ( integer) - Normalization Form C (NFC) - Canonical Decomposition followed by Canonical Composition

	      o Normalizer::FORM_D ( integer) -Normalization Form D (NFD) - Canonical Decomposition

	      o Normalizer::FORM_KC ( integer) - Normalization Form KC (NFKC) - Compatibility Decomposition, followed by Canonical Composition

	      o Normalizer::FORM_KD ( integer) - Normalization Form KD (NFKD) - Compatibility Decomposition

	      o Normalizer::NONE ( integer) -No decomposition/composition

	      o Normalizer::OPTION_DEFAULT ( integer) -Default normalization options
