# str(buffer, encoding, errors) should apply the 'ignore'/'replace' error
# handlers to any buffer source (array.array, memoryview, ...), the same way it
# does for bytes and bytearray.  Companion to str_from_buffer_snapshot.py.

    print("SKIP")

# Requires the decode error handlers (MICROPY_PY_BUILTINS_BYTES_DECODE_ERRORS).
# When the feature is disabled, invalid UTF-8 raises even with 'replace'.
    str(memoryview(b"\xff"), "utf-8", "replace")
except UnicodeError:
    print("SKIP")
    raise SystemExit
# array.array holding invalid UTF-8 bytes (typecode "B" keeps this endian-neutral).
