Most likely, I'd say.

Could you try:

\version "2.19.81"

#(define ((time-parenthesized-time up down upp1 downp1 upp2 downp2) grob)
   (grob-interpret-markup grob
     (markup
     #:override '(baseline-skip . 0)
     #:override '(font-name . #f)
     #:override '(font-encoding . fetaText)
     #:number
       (#:line (
           (#:center-column (up down))
           #:vcenter "("
           (#:center-column (upp1 downp1))
           #:lower 0.5 "+"
           (#:center-column (upp2 downp2))
           #:vcenter ")" )))))



\new Staff {
  \override Staff.TimeSignature #'after-line-breaking =
  #(lambda (grob)
    (newline)
    (pretty-print
      (ly:stencil-expr
        (ly:grob-property grob 'stencil))))

  \override Staff.TimeSignature #'stencil =
    #(time-parenthesized-time "21" "8" "12" "8" "9" "8")

  R1
}

The added code in `time-parenthesized-time` should make the markup
discard any font-name-setting you may have done before and forces it
to use 'fetaText.

The additional 'after-line-breaking-override displays the
stencil-expression in terminal.
It's a long list.
Of interest is for example the last section. Because font-name is #f
and font-encoding is 'fetaText a fall-back-font should be used, iiuc.
In my case it's "DejaVuSans":
[...]
  (translate-stencil
    (12.4918393700787 . 0.0)
    (translate-stencil
      (0.0 . -1.28037401574803)
      (translate-stencil
        (0.0 . 0.0)
        (glyph-string
          #<Font_metric (#f . 1.0)>
          "DejaVuSans"   <------------------------------
          7.029296875
          #f
          '((1.57059212598425
             (-0.512149606299213 . 3.07289763779528)
             0.0
             0.0
             "parenright")))))))

What's displayed for you?
