Invalid UTF-8 sequence in trimmed scriptlet output

[dansimko]

We have started to observe Testing Farm jobs failing with Fedora 41 and Rawhide failing on trimmed DNF output containing a 0xe2 byte, which cannot be interpreted as a valid UTF-8 sequence.

Relevant log excerpt:

The issue appears to be related to changes made in dnf5 5.2.7.0's to scriptlet output printing.
