All fonts for variables, functions, numbers and text are set to “Liberation Serif” plus attributes.
The operators for Sum, Product and Integral have a different style from the Coproduct and the other Integrals.
I would expect the Sum operator to be same as %SIGMA, with a “Liberation Serif” style, but it is shown as a “Liberation Sans”, for example.
I tried to find the options for the text/symbols used for the operators but wasn’t able to locate anything like that.
How could I fix this issue and have them all as “Liberation Serif” symbols?
