Unicode

Make-unicode

Basic constructor macro for unicode structures.

Syntax

(make-unicode [:codepoint <codepoint>])

This is the usual way to construct unicode structures. It simply conses together a structure with the specified fields.

This macro generates a new unicode structure from scratch. See also change-unicode, which can "change" an existing structure, instead.
