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".
