It is the case.  So, for example, é always represents the
character e-acute.  But in codepage 1252, e-acute is encoded
as the byte 0xE9, while in UTF-8 it is encoded as the two-byte
sequence 0xC3 0xA9.  I haven't studied the code, so I don't know
exactly where the conversion to and from entity references occurs,
but it's clear that whatever was converting to entity references was
assuing codepage 1252, and whatever was converting back again was
using UTF-8, so you get the conversion:

   0xE9  ->  é  ->  0xC3 0xA9

The same thing happens if you use numeric character references
instead of character entity references, because a numeric character
reference also represents a fixed character.
