当对 STIXTwoMath OTF 字体使用 \big 或 \left 或 \right 时，如何使用 \Udelcode 作为大分隔符？

我想使用 STIXTwoMath-Regular.otf 的 OTF 版本，以获取较大的分隔符，例如 (),[],{ },|,/,\vert,\Vert,\langle,\rangle,\lceil,\rceil， 等等，我需要修改通过 声明的所有分隔\DeclareMathDelimiter{}{}{}{}{}{}符fontmath.ltx

我通过\Udelcode ⟨char slot⟩ [=] ⟨fam.⟩ ⟨glyph slot⟩命令重新定义，仅获得几个分隔符的正确输出 (),[],|

使用 \big 或 \left 时，其中一些无法正确呈现，它正在加载默认的 LaTeX CMR 字体（CMEX10）

如何修改以获得 \left< . \right>、\langle、\rangle、\vert、\Vert、\lceil、\rceil 的正确字体加载（OTF），

此后，pdffonts显示

所以没有使用 Computer Modern 字形。
