# <a name='synopsis'></a>SYNOPSIS

package require Tcl 8\.5 9  
package require unicode 1\.1\.1  

[__::unicode::fromstring__ *string*](#1)  
[__::unicode::tostring__ *uclist*](#2)  
[__::unicode::normalize__ *form* *uclist*](#3)  
[__::unicode::normalizeS__ *form* *string*](#4)  

# <a name='description'></a>DESCRIPTION

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

# <a name='section2'></a>COMMANDS

  - <a name='1'></a>__::unicode::fromstring__ *string*

    Converts *string* to list of integer Unicode character codes which is used
    in __unicode__ for internal string representation\.

  - <a name='2'></a>__::unicode::tostring__ *uclist*

    Converts list of integers *uclist* back to Tcl string\.

  - <a name='3'></a>__::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* \(compatibility decomposition, followed by canonical composition\)\.

  - <a name='4'></a>__::unicode::normalizeS__ *form* *string*

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