Regex with ASCII and non-ASCII chars

[TOXiC]

Thx it work perfectly.
If I want to query a file stream?

    file = open(fileName, "r")
    text = file.read()
    file.close()

    regex = re.compile(u"(ÿÿ‹ð…öÂ)", re.IGNORECASE)
    match = regex.search(text)
    if (match):
        result = match.group()
        print result
        WritePatch(fileName,text,result)
    else:
        result = "No match found"
        print result

It return "no match found" (the file contain the string "ÿÿ‹ð…öÂ"
but...).
Thanks in advance for the help!
