Hello, while testing PyKDE4's modules with Python3, I noticed that the i18n() calls, which accept const char*, are not properly handled in Python 3 (both with API version 1 and 2):
In [2]: from PyKDE4.kdecore import i18n
In [3]: i18n("Test")
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-3-00970cb5d435> in <module>()
----> 1 i18n("Test")
TypeError: i18n(): argument 1 has unexpected type 'str'
It does work if I pass bytes, but that's not correct, as we're dealing with
strings here.
PyQt documentation states that char* or const char* would be acceptable with
strings (Python 3 strings).
As the original SIP file had custom code inside, I'm attaching it here. I
looked at it briefly, but I couldn't find why it didn't work.
Can anyone shed a light on this issue?
