You're right of course in this special case, since we're speaking about
pdksh on NetBSD, which doesn't seem to attempt to emulate the system's
version of echo(1).  Here's what I get with the real ksh (1993-12-28 k+)
on a FreeBSD system, where ksh's echo seems to use the BSD style of things:

$ echo '\0100\c'
$ print '\0100\c'

No, the builtins often cannot be relied up either, unless it's a builtin
such as "print", which is not available as an external command and as
such needs not retain any backwards compatibility.
A shell at compilation often configures itself to use the system's style
of doing things (so that it doesn't break scripts, isn't Unix a mess...)
