<br>
I was just playing with unicode strings and I notice a difference with CPython and IronPython. On CPython 2.7.2 I get the following<br>
<br>
>>> type(u"A")<br>
<type 'unicode'><br>
>>> type("A")<br>
<type 'str'><br>
<br>
On Ironpython the latest 2.7.2 Alpha 1 I get the following<br>
<br>
>>> type(u"A")<br>
<type 'str'><br>
>>> type("A")<br>
<type 'str'><br>
<br>
<br>
I decided to crack open the source and see where this type function is defined. I followed to the builtin.cs with the PythonModule but I got kind lost there. If anyone can provide some helpful hints that would be great.<br>
<br>
Thanks<br>
<br>
