Unicode

Change-unicode

Modifying constructor for unicode structures.

Syntax

(change-unicode x 
                [:codepoint <codepoint>])

This is an often useful alternative to make-unicode.

We construct a new unicode structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition
