Currently, the manpage says for -fexec-charset:

This explanation uses an absolute wording ("used for string and
character constants") that makes me expect that it affects *all* string
and character constants, possibly overriding what was set by u8 et
al. It was what drove me to ask the question on this list as I wasn't
sure whether there was something overlooked when implementing the c++11
standard in GCC, or intentionally extended. A simple addition such as
"This option does not affect string and character constants prefixed
with u8, u, or U, which are always stored in in the executable in the
charset requested by each respective prefix" would make any
misunderstanding impossible. To that end, I don't find the explanation
redundant.
