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"
