The manual (bash 4.1) says:
\xHH the eight-bit character whose value is the hexadecimal value
HH (one or two hex digits)
My bash (also 4.1) says:
imadev:~$ echo $'\x{123456}AB'
VAB
So, it looks like the undocumented feature that you asked us to test
for you is only respecting the last two hex digits inside the curly
braces. Since none of this behavior is documented, I wouldn't count
on bash retaining that behavior in the future.
