Serialize:
Do BFS traversal
store the nodes (character) in the string buffer as they are explored

Deserialize:
In the given string buffer:
root -> first element
left child -> 2i
right child -> 2i+1
// i is the index as you travel through the buffer. So every index will have a left and a right child as defined above.

It doesn't work when the tree is not a complete binary tree.

I think it will work if we can put a designated {{null}} value.

Find the Inorder and pre order traversal of the tree and store it as a string.
Use the same inorder and pre order traversal to create the binary tree.
