Ok, I learn new things every day. :)

:-) It might go back at least as far as IBM's GDDM from 1979. In IBM's context, I think a codepoint would have represented a numeric value which was translated by lookup in a (single- or double-byte) codepage to a glyph, with the obvious gross differences depending on whether the codepage family was ASCII or EBCDIC. I think Unicode usage is fairly consistent with that, assuming that codepage lookup was brushed under the carpet as a manufacturer-specific detail.
