    Ugh.

    We recently saw a problem of this type, but I don't think it's the
    same,
    or at least not exactly the same, although it could be similar.

    Can you please compile this code ? It should prints lots of stuff
    to the
    log. Send that back.

    \version "2.24.0"

    #(define-markup-command (debug layout props arg) (markup?)
        (let ((stil (interpret-markup layout props arg)))
          (pretty-print (ly:stencil-expr stil)
                        (current-error-port))
          (flush-all-ports)
          stil))

    \markup \debug \line { N is wrong. }
    \markup \debug \line { \bold N is fine. }




(combine-stencil
  (utf-8-string
    "LilyPond Serif 3.8662109375"
    "N"
    (translate-stencil
      (0.0 . 0.0)
      (glyph-string
        #<Pango_font (#f . 1.0)>
        "TimesNewRomanPSMT"
        3.865234375
        #f
        ((1.604735433070866
          (-0.023640238988681103 . 1.4566921874999998)
          0.0
          0.0
          "N"))
        "/System/Library/Fonts/Supplemental/Times New Roman.ttf"
        0
        "N"
        ((1 . 1)))))

I get this output. The correct, bold one names a particular glyph and the other does not. Don't know if that is important.

OK, at least two things are going wrong here.

Try using the official binaries while they fix this.

Best,
Jean

First, could you please send me the file that you have under "/System/Library/Fonts/Supplemental/Times New Roman.ttf"? I would like to understand what is going wrong with the N letter in this font. Better send it to me privately, as I suspect the list won't let it pass due to file size restrictions (or use a sharing service). Second, Homebrew's way of packaging LilyPond seems to have missed a build change in 2.24, because LilyPond should not be using Times New Roman here in the first place, but its normal default text font C059.
