What is the idea?

The spyder feedstock contains an ico file that cannot be decoded with UTF-8.

xref: conda-forge/spyder-feedstock#177

• Build log: 24.txt

This is triggering the test

conda-build/conda_build/noarch_python.py

Line 29 in ee7d0ce

sys.exit(f"[noarch_python] Noarch package contains binary script: {fn}")

to fail causing the build to fail

Why is this needed?

Handle packaging edge cases like this

What should happen?

The build should pass

Additional Context

Maybe the ico file could be moved, but ensuring that icons work well is generally difficult.
