Replaced elements (eg. elements) are rendered externally and behave as an
atomic opaque box in CSS. In general, they may or may not have intrinsic
dimensions. But the only replaced elements currently supported in WeasyPrint
are images with intrinsic dimensions.

This is different from the :meth:`str.lower` method of Unicode strings
which also affect non-ASCII characters,
sometimes mapping them into the ASCII range:
>>> keyword = 'Bac\N{KELVIN SIGN}ground'
>>> assert keyword.lower() == 'background'
>>> assert ascii_lower(keyword) != keyword.lower()
>>> assert ascii_lower(keyword) == 'bac\N{KELVIN SIGN}ground'
