In that spirit (and sorry for hijacking your
posting): I noticed that the %h and %H conversion
specifiers use an 'x' (letter x) and a '*' (asterisk)
to form numbers like 3.1 x 10^4.

It would be lovely if they used the "multiplication
sign" (U+00d7) and the dot operator (U+22c5 - or
alternatively U+00b7) instead.

I could imagine a general user option for such 
situations, eg:

set character minus <character>
set character times <character>

That would also allow an easy fallback for the 
situation that the user's installed font does
not supply glyphs for the required "special" chars.
