Assuming that you want to find runs of \uXXXX escapes, simply use
non-capturing parentheses:

    pat = re.compile(u"(?:\\\u[0-9A-F]{4})")

Doesn't work for me:

pat = re.compile(u"(?:\\\u[0-9A-F]{4})")

it helps if you cut and paste the right line...  here's a better version:

    pat = re.compile(r"(?:\\u[0-9A-F]{4})+")
