You'd use
\markup \replace #`(("100" . ,#{ \markup \concat { "1" \translate-scaled
#'(-0.5 . 0) "00" } #}) ("dpi" . "dots per inch")) "A 100 dpi."
if it were supported, which it isn't. Text replacements are purely
string-to-string at the moment. Logically that should not be required
since the replacements happen in the course of creating a stencil from a
string in ly:text-interface::interpret-string which has all the
information it needs to also properly interpret markups.
But it would make for quite trickier code paths.
