paste text as binary?

[Erhy]

Hello,

 a long used program shows instead german letter

ü 

FC

(the text is not stored as file)

if I copy the text and paste it in VIM I see instead

für Anschluss

f<dc8a><dc01>nschluss

I think it is because Microsoft make UTF8 as default encoding format.

Have I a chance to restore the text.

Thank you for tipps
