Obviously, you are right, thanks.

The subroutine "git tree" generates the tree view. It stores the output
of "git ls-tree -z ..." in an array named "@entries". Printing the content
of this array yields the following result:
00644 blob 6419cd06a9461c38d4f94d9705d97eaaa887156a 520 Gütekriterien.txt
This leads to the "doubled" encoding. Declaring the encoding in the call
to open yields the following result:
100644 blob 6419cd06a9461c38d4f94d9705d97eaaa887156a 520 Gütekriterien.txt
