I have not tested with the last version. So I'm assigning this to me for now to
at least analyse the problem on Windows.

I did install gpg4win 2.2.3 which does include the fix for Umlaut. I prefer to
use GPA as frontend for encryption and decryption. For decryption, I did link
.gpg to be always opened with GPA. Unfortunatly if the File or Path to the .gpg
has an Umlaut included the GPA GUI crashes. Only if I use the open button from
GPA the file can be added to the GPA frontend and decrypted. For non-umlaut
files the link to open .gpg works fine. Do you also work on GPA bugs or do I
have to report this under the GPA category?
Thank you & regards,
