Triggering UnicodeDecodeError

How UnicodeDecodeError is raised and how to catch it.

python
# Triggering and catching UnicodeDecodeError
try:
    b"\xff".decode("ascii")
except UnicodeDecodeError as e:
    print(f"Caught UnicodeDecodeError: {e}")
    print(f"Type: {type(e).__name__}")

UnicodeDecodeError is raised when raised when decoding bytes to a string fails. Always catch specific exceptions rather than bare except clauses.

Handling UnicodeDecodeError

Basic error handling pattern for UnicodeDecodeError.

python
# Safe handling pattern
def safe_operation():
    try:
        b"\xff".decode("ascii")
    except UnicodeDecodeError:
        print("Operation failed gracefully")
        return None

result = safe_operation()
print(f"Result: {result}")

Wrapping risky operations in try/except blocks prevents your program from crashing.
