# Helper to handle String encodings. The +str+ and +encoding+ parameters
# must be Strings and an ArgumentError will be raised if not. This ensures
# that the encode() helper can be used regardless of whether Encoding exits.
# The helper is a no-op (i.e. passes through +str+ unmodified) if the
# :encoding feature is not enabled (see with_feature guard). If the
# :encoding feature is enabled, +str+.force_encoding(+encoding+) is called.
