Need 9th Charachter from LEFT in text string

Hello,

I am looking for help with a formula. What I want is a formula that will give me the 10th character in a text string. For example if I have the following text string:

A.00578.158

The formula should return 1 as that is the 10th character in the string (also including decimals)

I used the formula = LEFT(A1,10) but that returned the entire text string up to the 10th character = A.00578.1

I just need something that will return the 10th character from the left.

Thanks
