Error due to special characters like é in France in the Windows user name

[softsyst]

On first start, or if e.g. after the installation of a new version a fresh config file, e.g. qirx4.config is being created, the software replaces in the config file some placeholder with the name of the logged-in user, for being able to create its data directory tree in the AppData folder of Windows.
With the French é (and possibly other special characters of other languages) this does not work properly. Instead of the é, a questionmark ? is written into the config file.
This has the consequence of extremely luggish working of qirx, and other strange and erroneous behavior.

The issue is currently under investigation.

As a workaround, the config file (e.g. qirx4.config) should be manually edited in a text editor, and all questionmarks ? replaced with the proper character like the é. After this procedure everything should work as intended.

Remark: The AppData directory is located in Windows here:
C:\Users\<user name>\AppData\Local\...
or from within QIRX by pushing the "Home" button on the top line.

Version 4.2.2 should fix it. Please report if you observe otherwise.
