Have a pointer symbol "*" in block

[codingspirit]

Hi,

I'm trying to have a block like this:

+------------+
|int* func() |
+------------+

* stand for pointer so I'd like to keep it exactly as *. But it will be transferred into a big blank if I do so in raw rst file. Tried \* and #* as well, none of them meets my requirements.

Is there a way to have a pointer symbol in a block? Thanks a lot
