Regex with ASCII and non-ASCII chars

[TOXiC]

Hello everybody.
How I can do a regex match in a string with ascii and non ascii chars
for example:

regex = re.compile(r"(ÿÿ‹ð…öÂty)", re.IGNORECASE)
match = regex.search("ÿÿ‹ð…öÂty")
if match:
result = match.group()
print result
else:
result = "No match found"
print result

it return "no match found" even if the two string are equal.
Help me please!
Thx in advance :)

regex = re.compile(r"(ÿÿ?ð?öÂty)", re.IGNORECASE)

if match:
result = match.group()
print result
else:
result = "No match found"
print result

For equal strings you should get a match:

>>re.compile("Zäöü", re.IGNORECASE).search("yadda zäöü yadda")

<_sre.SRE_Match object at 0x401e0a68>

>>print _.group()

zäöü

For case ignorance your best bet is unicode:

>>re.compile(u"äöü", re.IGNORECASE|re.UNICODE).search(u"ÄÖÜ")

<_sre.SRE_Match object at 0x401e09f8>

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!

Convert the bytes read from the file to unicode. For that you have to know
the encoding, e. g.

file_encoding = "utf-8" # replace with the actual encoding
text = text.decode(file_encoding)

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...).

I think the best way is to search hex value in the file stream but I
tryed (in the regex) \hxx but it don't work...
