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  decomposition),  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 "\u0410\u0411\u0412\u0413"
              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
              %
