Why doesn't the build stop at that point?

I fixed a similar FTBFS in a different package just 2 hours ago,
so that would have sound familiar:

Which version of the TeX Live packages do you have installed?

This seems to be related to the 2018 packages that entered unstable

The problem is the opposite:
The character is ISO-8859 encoded, and therefore not valid UTF-8.

In src:alliance I used \usepackage[latin1]{inputenc} to fix it.
