Scapy - Raw layer to string and into a wx.TextCtrl

Question

I'm using scapy to show all layers of a packet and when the packet has a UDP layer and Raw it sometimes gives me an 'UnicodeDecodeError: 'charmap' codec can't decode byte...' and I dont know what to do .. help? this is the line of code that makes trouble :

 self.txt.SetValue(str(pkt.getlayer(Raw).load))

I need a way to show the Raw data in the TextCtrl.

Try passing the data as unicode instead of a string:

self.txt.SetValue(u'%s' % (pkt.getlayer(Raw).load))

I wouldn't be too surprised if this didn't work though, so be sure to read up on how to use unicode in Python:

• https://docs.python.org/2/howto/unicode.html

You should also check out the following articles:

• http://wiki.wxpython.org/UnicodeBuild
• http://kevino.theolliviers.com/python-unicode.html
• http://zetcode.com/wxpython/in18/
• http://wiki.wxpython.org/Internationalization

If all else fails, you can always try converting the unicode to ascii using this fun package:
