code-to-utf16-char

Arguments: code

The code argument must be a fixnum. It is interpreted as a Unicode character code and converted into the UTF-16 encoding used internally in the Allegro CL string representation.

Returns two values:

1. A character and nil: if code is smaller than #x10000.
2. A high-surrogate-character and a low-surrogate-character if code is in the high Unicode range.
3. nil and nil if code is not a valid Unicode code point.

See iacl.htm for more information on international characters and external formats.
