I agree it isn't the right term and I have also been under the
impression that the right term doesn't yet exist in the standard.

I spent a little time searching and came across
http://eel.is/c++draft/lex#ccon-9.sentence-1:

    "A universal-character-name is translated to the *encoding, in the
    appropriate execution character set*, of the character named."

This suggests that "the encoding of the execution character set" might
be better (for now). If you agree, I'll make that change.

My interpretation of that sentence (and thank you, I wasn't aware that
links existed for individual sentences!) is that the execution character
set is locale dependent in the sense that the Visual C++ compiler
defaults the execution character set to the current locale at
compile-time, but can be overridden with the /execution-charset option.

Indeed, I'm looking forward to that paper landing in a near future
standard and would expect the wording I proposed to be impacted by it! :)
