Unicode codepoints are not even printable.
A single printable "character", as selectable by a single cursor step,
can consist of multiple codepoints, even (or just) in Unicode.
That's why I'd expect that the FPC documentation includes a glossary and
definition of the terms, which should be used in the documentation and
