>Because "bijective" is not so well understood by anyone born before >1952 or so. I was born before 1952 and understand "bijective" just fine. OTOH, "round trip" is something I specify when I am buying travel tickets. OTOH, a mapping from an EBCDIC code page to a Unicode code page can't be bijective, only injective, and there is no round trip for, e.g., Unicode->EBCDIC->Unicode, regardless of which EBCDIC code page and Unicode transform you use. Contrast "left inverse" with "right inverse". -- Shmuel (Seymour J.) Metz, SysProg and JOAT ISO position; see <http://patriot.net/~shmuel/resume/brief.html> We don't care.
