Weird indeed.

Some of that sounds like using the number command may be the problem, 
because the font doesn’t contain many normal glyphs. Try experimenting 
with the normal-text markup command.

However, still more weird is that I don’t get any of those problems: the 
markup itself looks OK, but there’s some white space instead of the 
start of the staff symbol. This is on Ubuntu 16.04, with Lily 2.19.82.

I’d experiment in this direction with the markup:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.19.82"

\language "english"

#(define-markup-command (timesig-paren layout props opening?) (boolean?)
   (interpret-markup layout props
     (markup #:normal-text
       #:override '(font-size . 6)
       #:scale '(0.5 . 1)
       #:vcenter
       (if opening? "(" ")"))))


#(define ((time-parenthesized-time up down upp1 downp1 upp2 downp2)
grob)
   (grob-interpret-markup grob
     (markup #:override '(baseline-skip . 0) #:number
       (#:line (
           (#:center-column (up down))
           #:timesig-paren #t
           (#:center-column (upp1 downp1))
           #:normal-text #:lower 0.5 "+"
           (#:center-column (upp2 downp2))
           #:timesig-paren #f )))))

\new Staff {
  \override Staff.TimeSignature.stencil = #(time-parenthesized-time
"21" "8" "12" "8" "9" "8")
}
%%%%%%%%%%%%%%%%%%%%%

Output attached – I don’t know where that whitespace comes from.

Best, Simon
