Hm, this doesn't even work with Python 3:

My mistake. I should have tested better.

data = array.array("u", u"x"*1000)
data[100] = "y"
re.search("y", data)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/usr/lib/python3.4/re.py", line 166, in search
     return _compile(pattern, flags).search(string)
TypeError: can't use a string pattern on a bytes-like object

You can search for bytes

re.search(b"y", data)
<_sre.SRE_Match object; span=(400, 401), match=b'y'>
data[101] = "z"
re.search(b"y", data)
<_sre.SRE_Match object; span=(400, 401), match=b'y'>
re.search(b"yz", data)
re.search(b"y\0\0\0z", data)
<_sre.SRE_Match object; span=(400, 405), match=b'y\x00\x00\x00z'>

but if that is good enough you can use a bytearray in the first place.

Maybe I'll try that. Thanks for the suggestions!
