unicode - Implementation of Unicode normalization


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


::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.


% ::unicode::fromstring "\u0410\u0411\u0412\u0413"
1040 1041 1042 1043
% ::unicode::tostring {49 50 51 52 53}
% ::unicode::normalize D {7692 775}
68 803 775
% ::unicode::normalizeS KD "\u1d2c"
