For the record, it is easy enough to create this invisible object.
The Maxima parser already recognizes \ (i.e. backslash preceding
a space) as the symbol which has the name " ".
So we could do this (although I don't know that it's useful in
the present context).
texput (\ , "{}");
tex (\ ^u);
=> $${}^{u}$$
FWIW
