Improve "invalid byte sequence for encoding" message

Browse Source 
It used to say

ERROR:  invalid byte sequence for encoding "UTF8": 0xdb24

Change this to

ERROR:  invalid byte sequence for encoding "UTF8": 0xdb 0x24

to make it clear that this is a byte sequence and not a code point.

Also fix the adjacent "character has no equivalent" message that has
the same issue.
