[Ironpython-users] Unicode

I just noticed that the non-BMP Unicode Literals don't seem to work correctly in IronPython, this seems to work correctly in cPython 2.7.8:

Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)] on win32
>>> u"\U00010042"

IronPython 2.7.4 ( on .NET 4.0.30319.18444 (32-bit)
>>> u"\U00010042"

I guess this truncation is caused by the UTF-16 nature of .NET strings. I guess the most sensible thing IronPython could do here is to create the correct surrogate pair:

>>> System.Text.Encoding.UTF32.GetString((0x42, 0, 1, 0))
