[New-bugs-announce] [issue29294] ctypes.windll.LoadLibrary refuses unicode argument

[Thomas Heller]

New submission from Thomas Heller:

ctypes.windll.LoadLibrary refuses unicode argument; this is a regression in Python 2.7.13:

Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:42:59) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from ctypes import windll
>>> windll.LoadLibrary(u"kernel32.dll")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\ctypes\__init__.py", line 440, in LoadLibrary
    return self._dlltype(name)
  File "C:\Python27\lib\ctypes\__init__.py", line 362, in __init__
    self._handle = _dlopen(self._name, mode)
TypeError: LoadLibrary() argument 1 must be string, not unicode
>>>

It did work in Python 2.7.12 and before:

Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from ctypes import windll
>>> windll.LoadLibrary(u"kernel32")
<WinDLL 'kernel32', handle 77360000 at 3606f10>
>>>
