       Object oriented style

SYNOPSIS

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

DESCRIPTION

       Procedural style
       bool normalizer_is_normalized (string  $input, [string  $form = Normalizer::FORM_C])

	Checks if the provided string is already in the specified normalization form.

PARAMETERS

	      o $input
		-The input string to normalize

	      o $form
		- One of the normalization forms.

RETURN VALUES

       TRUE if normalized, FALSE otherwise or if there an error

EXAMPLES

       Example #1

	      normalizer_is_normalized(3) example

	      <?php
	      $char_A_ring = "xC3x85"; // 'LATIN CAPITAL LETTER A WITH RING ABOVE' (U+00C5)
	      $char_combining_ring_above = "xCCx8A";	// 'COMBINING RING ABOVE' (U+030A)

	      $char_orig = 'A' . $char_combining_ring_above;
	      $char_norm = normalizer_normalize( 'A' . $char_combining_ring_above, Normalizer::FORM_C );

	      echo ( normalizer_is_normalized($char_orig, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
	      echo '; ';
	      echo ( normalizer_is_normalized($char_norm, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
	      ?>

       Example #2

	      OO example

	      <?php
	      $char_A_ring = "xC3x85"; // 'LATIN CAPITAL LETTER A WITH RING ABOVE' (U+00C5)
	      $char_combining_ring_above = "xCCx8A";	// 'COMBINING RING ABOVE' (U+030A)

	      $char_orig = 'A' . $char_combining_ring_above;
	      $char_norm = Normalizer::normalize( 'A' . $char_combining_ring_above, Normalizer::FORM_C );

	      echo ( Normalizer::isNormalized($char_orig, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
	      echo '; ';
	      echo ( Normalizer::isNormalized($char_norm, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
	      ?>

       The above example will output:

       not normalized; normalized

NAME

       unicode - Implementation of Unicode normalization

SYNOPSIS

       package require Tcl  8.3

       package require unicode	1.0

       ::unicode::fromstring string

       ::unicode::tostring uclist

       ::unicode::normalize form uclist

       ::unicode::normalizeS form string

_________________________________________________________________

DESCRIPTION

       This is an implementation in Tcl of the Unicode normalization forms.

COMMANDS

       ::unicode::fromstring string
	      Converts string to list of integer Unicode character codes which is used in unicode for internal string representation.

       ::unicode::tostring uclist
	      Converts list of integers uclist back to Tcl string.

       ::unicode::normalize form uclist
	      Normalizes  Unicode  characters  list  ulist according to form and returns the normalized list. Form form takes one of the following
	      values: D (canonical decomposition), C (canonical decomposition, followed by canonical composition),  KD	(compatibility	decomposi-
	      tion), or KC (compatibility decomposition, followed by canonical composition).

       ::unicode::normalizeS form string
	      A  shortcut  to ::unicode::tostring [unicode::normalize $form [::unicode::fromstring $string]].  Normalizes Tcl string and returns
	      normalized string.

EXAMPLES

       % ::unicode::fromstring "u0410u0411u0412u0413"
       1040 1041 1042 1043
       % ::unicode::tostring {49 50 51 52 53}
       12345
       %

       % ::unicode::normalize D {7692 775}
       68 803 775
       % ::unicode::normalizeS KD "u1d2c"
       A
