for the fixed Gpg4win 3.1.13
Unfortunately this new release has a regression affecting users with non-ascii account names. See T5098.
The only useful workaround is to use a different user name or use set the environment variable GNUPGHOME to a directory which has only ASCII characters in its name. We are working on a solution but it turned out to be more work than originally expected. Please stay tuned.
Background: A fix for gpgtar (T4083) had an unfortunate side effect for home directories (and thus user accounts) with non-ASCII characters. This even affects simple Latin-1 (code page 850 et al) Umlauts and not just 16 bit Unicode characters. The latter have always been problematic. The fix in the works will bring nearly complete Unicode support to GnuPG/gpg4win.
