This is laziness, intended to get around the "problem" of supplementary code
points instead of handling them like any other code points. This reminds me
of the Java bastardization of UTF-8, in which U+0000 is encoded 0xC0 0x80 so
that no character string will ever contain the byte 0x00. (Nobody has ever
explained to me why a character string would contain U+0000 in the first
place.)
I have argued in the past that in some cases, semi-conformant Unicode
implementations might be better than non-Unicode solutions. But creating a
new UTF to get around your product's lack of real Unicode support *and then
expecting others to use your hack* is a different matter entirely. Just bite
the bullet and support UTF-8. It's not that hard.
