8 Dot Braille Code Cheat Sheet

When a braille display is connected to an iOS device and input is set to 8 dot mode, one can enter symbols such as the at sign with dots 4-7.

I have the list of the standard punctuation found on qwerty keyboards. What I cannot find is a list of all the other codes, for foreign characters and other special symbols. This is for the U.S. Can someone point me to a resource for this? Thanks.
