[austinyu]

Describe the bug

When running bandit pre-commit, if the source code contain non ascii characters, pre-commit hook will throw an ugly error message that it could not encode those characters.

Reproduction steps

put these two files under one folder

• .pre-commit-config.yaml

# pre-commit autoupdate

repos:
  - repo: https://github.com/PyCQA/bandit
    rev: 1.8.3
    hooks:
      - id: bandit
        args: [-c, pyproject.toml]
        additional_dependencies: ["bandit[toml]"]

• foo.py

print("❌ Failed to copy workspace file 🌟")
# '\U0001f31f'
print("🌟 Welcome back")

Run pre-commit install Run pre-commit run --all-files
