problem with german umlauts

[Reinhard Irmer]

I have installed GnuPG 1.4.11 from the GnuPT-site and GnuPG 2.0.16 (gpg4win
2.1.0ß) under winxp. codepage is 437. The verify-result is OK in both
versions, but only the umlauts are making trouble:
In Gpg v1.4 it looks like http://666kb.com/i/boauplx7p51xe92uc.jpg
(demolitioned umlauts), but in Gpg v2.0.16 :
http://666kb.com/i/boauqrekhb2thrhyc.jpg (umlauts OK)

Whats to do, to make version 1 showing correctwritten results?
