Visual clarity.
It is easier to visually segment:
U+00F0 U+0CAE U+4EBD U+ABBD U+0880
than it is to visually segment:
U00F0 U0CAE U4FBD UABBD U0880
They are logically equivalent as representations, of course,
but for *reading* purposes, it is easier to see the hex as
a unit if a nonletter symbol separates the leading (letter)
symbol from the digits and letters in the hex.
Some people accomplish the same thing with casing, which
can work pretty well for the letters, but doesn't help so
much with the cap-height digits:
U00f0 U0cae U4fbd Uabbd U0880
