I have used newtxmath package and experienced some issues, the package is changing the math font in my entire document. Is there a way to use this package for one symbol so its only available locally, when the particular symbol is called.
\usepackage{newtxmath}
$\vmathbb{1}$
unicode-math. – Davislor Sep 17 '21 at 13:39\mathversion{times}, or else define one symbol as, e.g., ``\varforall` and use it as appropriate. Legacy TeX is limited to only sixteen math alphabets throughout the entire document, however. XeTeX and LuaTeX do not have that limit. – Davislor Sep 17 '21 at 13:42
