ValueError: unsupported format character '?' (0xa) at index 24

[dev107]

With all tries, I got a bunch of following errors:

ValueError: unsupported format character '?' (0xa) at index 24
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Logiciel\WinPython-32bit-3.4.4.4Qt5\python-3.4.4\lib\tkinter_init_.py", line 1538, in call
File "nsf2x.py", line 612, in doConvert
File "nsf2x.py", line 638, in doConvertDirectory

Its running on Windows 7, Lotus Notes 8.5.3 and Outlook 2010. I also tried mbox/eml. Same summary. Any hints?

I am having the same problem and using the same version(s) as @mtbandi
@adb014 any idea how to fix this? I have tested version 1.3.6 (x86). 1.3.3 and 1.3.5 generally not working.

Thanks

Unfortunately, same error.

@adb014 you have any idea, or is this project completely abandoned? Thank you.

Can’t test ´cause I no longer have NOTES, which was kind of the point of writing this code Le 11 nov. 2025 à 10:53, ballerbude ***@***.***> a écrit :ballerbude left a comment (adb014/nsf2x#23) Unfortunately, same error. @adb014 you have any idea, or is this project completely abandoned?
