When replacing the literal "double00" with "foobar" in your function,
the same error occurs for me:

    test=# select doublezero();
    INFO:  foobar
    CONTEXT:  PL/Perl function "doublezero"
    ERROR:  invalid byte sequence for encoding "UTF8": 0x00 at line 6.
    CONTEXT:  fonction PL/Perl « doublezero »

Anyway it's not clear what you expect. PG doesn't support UTF-16,
and even if it did, it wouldn't accept such strings when the current
encoding is UTF-8.
If Active Directory wants UTF-16LE, you have to do that conversion, but
don't pass the result back to postgres in this format.
