Subject: Fix bug when slicing a string with broken encoding

Commit aa2a428 introduced a bug where non-embedded string slices copied
the encoding of the original string. If the original string had a broken
encoding but the slice has valid encoding, then the slice would be
incorrectly marked as broken encoding.
