GHSA-F2JV-WJJC-2C94 uutils coreutils has an Uncaught Exception When Encountering Valid but Non-UTF-8 Paths

The sort utility in uutils coreutils is vulnerable to a process panic when using the --files0-from option with inputs containing non-UTF-8 filenames. The implementation enforces UTF-8 encoding and utilizes expect, causing an immediate crash when encountering valid but non-UTF-8 paths. This diverg...
