Unable to directly type § in Anvil, Book and Quill, or chat

In Book and Quill, we can format text by using § (section sign) and an alphanumeric character. However, in order to input the section sign, we have to copy the character from a text editor or web browser and paste it into the Book and Quill.

I would be expecting that, with my QWERTY keyboard, I can type the section sign directly in the Book and Quill, especially when I hold Alt and press 0167 on my Numpad.
