Round-trippability.  Unix and MS-DOS both use ASCII, but have different
line-end conventions.  We do not want to have separate conversion
tables (to and from Unicode) for different operating systems' notion
of plain text.  (Bad enough we have to handle different charsets/
code pages, but at least they can be OS-independent.)

So there is a Unicode equivalent for every control character
(33 in C0, 32 in C1, 64 in EBCDIC), and line-end differences
have to be adjusted above that level.

I.e. at the XML level.
