I'm trying to replicate a specific script 'X' that I'm seeing in a textbook:
This lines up pretty well with the computer modern script X:
But I'm using the unicode-math package, and the script characters in the default font (latin modern) look nothing like the script characters in computer modern (even though it's supposed to just be a modernized version). The unicode-math documentation includes a symbol list of a few included fonts, of which the concrete math font gets the closest:
But I really don't like the uniform stroke thickness - it really doesn't match with the rest of the characters on the page (since I'm otherwise using computer modern / latin modern).
Does anyone know of an OpenType math font that has a similar script X that I'm looking for?



unicode-mathpackage when not using pdfLaTeX to compile your document? If one doesn't loadunicode-math, the output of\mathcal{X}is the same under both pdfLaTeX and LuaLaTeX. – Mico Oct 22 '23 at 16:25
