Unicode codepoints have almost nothing to do with this, since nowadays
encode-char is mostly a no-op with Unicode character set.  Its main
use is with non-Unicode charsets, and there we cannot apply the
knowledge of the Unicode code-space, we cannot even assume the
code-space is populated densely as in Unicode.
