使用組合字體設定無襯線數學字型：大積分錯誤

我目前正在嘗試在 lualatex 中使用組合字體建立無襯線字體。在測驗中，我使用 TeX Gyre Pagella Math 作為基本數學字體，並嘗試從其他數學和文字字體中提取字形。

它已經適用於數字和字母，但現在我陷入了積分。我可以使用 TeX Gyre Dejavu Math 中的 textstyle 積分，但 displaystyle 積分是錯誤的。有人知道如何修正這個問題嗎？

（這是一個測試文件！所以它並沒有試圖變得漂亮。例如，腳本樣式字體使用其他粗細，以便可以更好地查看組合是否有效）。

% better start with a real math font, so that

\setmathfont{TeX Gyre Pagella Math}%

% Perhaps some other symbol fonts will need setup too

如果你只是使用 unicode-math

% better start with a real math font, so that
% unicode-math sets everything up
\setmathfont{TeX Gyre Pagella Math}%

所以刪除所有組合字體的東西，然後添加\showoutput你看到的

.....\l_fontspec_font ∫
....\glue(\thinmuskip) 1.82497
....\l_fontspec_font f

對於文字樣式\int f但是

.......\l_fontspec_font
