Is there a way to introduce a new integration symbol? Specifically I want to be able to use ⨍. I have no problem entering it into mm, but the size does not change like the standard \int does.
As commented by m_goldberg:
The unicode character 2a0d is not recognized by Mathematica as having any special significance and, therefore, there is no built-in support for formatting it as there is for ∫ (
Moreover, if you enter it as a Unicode character using
\:2a0d Mathematica displays it as an empty box. It doesn't look like there's any support for doing what you want.
