[issue25778] winreg.EnumValue does not truncate strings correctly

[Eryk Sun]

Eryk Sun added the comment:

Based on matplotlib's win32InstalledFonts function [1], I created a small test to check the data strings returned by winreg.EnumValue for the presence of null characters. I tested on Windows 7 and 10 but couldn't reproduce the problem. Please run nullcheck.py to check the results on your system.
