If you want to bind "C-x = =" to 'describe-char' you first have to
unbind "C-x =" keybinding as it's already bound to
'what-cursor-position'.

To unbind the "C-x =" place the following in your init.el file:
(global-unset-key (kbd "C-x ="))

Now it'll be possible to bind 'describe-char' to "C-x = ="
(global-set-key (kbd "C-x = =") #'describe-char)

Now you if you still need to have easy access to 'what-cursor-position'
command, bind it to something else. For example let's bind it to
"C-x = w"
(global-set-key (kbd "C-x = w") #'what-cursor-position)

It is not possible to have "C-x =" bound to a function and "C-x = ="
bound to some other function simultaneously. A key combination is either
a complete key sequence or a prefix key. It can't be both.

kbd takes key sequence strings like described in the manual, like "C-h
k", "C-x x =" etc. This key sequence "<C-x-x-=>" basically means type
left angle bracket, right angle bracket, Control, x, = all at the same
time.
