[IronPython] Reading Text files with open

[Michael Foord]

Hello all,

If I create a file with the following code:

open(r'c:\temp\test.txt', 'w').write('\xa33')

And then read it in using the Python 'open', I get different results 
with Python and IronPython:

CPython 2.4.4:

 >>> data = open(r'c:\temp\test.txt').read()
 >>> data
'\xa33'
 >>> ord(data[0])
163

IronPython 1.1:

 >>> data = open(r'c:\temp\test.txt').read()
 >>> data
'?3'
 >>> ord(data[0])
63

If I use the 'rb' flag with IronPython then the right thing happens, but 
this isn't binary data...

Is there any way round this - I guess it is a consequence of .NET strings.

Michael
