Compound text is an old multi-charset encoding (in the spirit of iso
2022, from before the rise of unicode).  The ICCCM specifies the a
some (mostly obsolete) properties are to be set in this encoding,
unless I misremember, and selection owners are probably also expected
to handle it if it is requested.

It has very little relevance in todays Unicode-dominated world, and we
should probably look if we move the support for this entirely into the
X11 backend and not expose it in apis.
