I’m looking for the math symbol for circonference arc between two points A and B to insert in a LibreOffice writer document without success. It should be like this : AB but with an little arc above the letters AB
Type AFE20
Select FE20, press Alt+X
Type FE21B
Select FE21, press Alt+X
If do you change AB to smallcaps, it will be shown better.
The font color of the left character gives it color to the arch.
