Hi,
I have a standalone python executable created using PyInstaller
(modified to support Python 3) on Linux. This executable was running
well with Python 3.0.1. But on Python 3.1.1 it is breaking with
UnicodeEncodeError.
Executable created with same code on Windows it is running without any
error.
After debugging the Python code I found that the PyInit__tkinter in file
_tkinter.c is not able to encode the executable name or path when it
finds characters other than 'a' ('A') through 'p' ('P') at position
multiple of 4 (0 based).
For example if my executable name is "setup" it finds 's' at the
position 0 and breaks with UnicodeEncodeError.
NOTE: If I change the name to "etup" (removed 's') it is executing well.
And also if I replace 's' with any character 'a' through 'p' it is
working.
This is happening because here by default 'strict' error handler is
being used.
I tried to play a little with the Python code. And modified
PyInit__tkinter() to used "surrogatepass" error handler while it is
encoding the Unicode string with utf-8 encoding.
i.e. I replaced
cexe = PyUnicode_AsEncodeString(uexe,Py_FileSystemDefaultEncoding,NULL);
with
cexe = PyUnicode_AsEncodeString(uexe,Py_FileSystemDefaultEncoding,
"surrogatepass");
My executable started running without changing its name.
I have no idea whether this is a feature or bug in PyInit__tkinter().
Is there any way I can specify PyInit__tkinter to use "surrogatepass"
instead of "strict" error handler.
Please help me with your suggestions.
Thanks,
Lakshman
