Research direction
Start by reproducing the issue with the shown QUOTING_STYLE=$'\xFF' command and compare the output with gnuls. Trace how ls reads and validates QUOTING_STYLE, then locate the existing ls test entry point; done means invalid UTF-8 produces a warning while retaining the expected listing behavior.
Written by the indexing model from the issue text.
