Can't convert string to hex int to use in chr()

I'm trying to write a code to print chemical equations in a readable form. I've got all other parts working aside from the subscripts. I know the subscripts will range from 1 to 9, and the hex code is 0x2081 - 0x2089 accordingly.
If the user inputs O_2, it will attach the needed 2 to the hexadecimal to create 0x2082, giving me the subscript 2. However, I can't convert the string '0x2082' into a usable type for chr.
uni = '0x208'
el = input("Enter element (with optional underscore): ")
if ('_' in el):
end = str(el[len(el)-1])
hex_code = uni + end
print(hex_code)
sub = chr(int(hex_code))
Anything to point me in the right direction would be appreciated.

This works:
In [1]: chr(0x2082)
Out[1]: '₂'
So all you need to do is something like this:
text = 'O_2' # take from user input
subzero = 0x2080
subchr = chr(subzero + int(text[-1]))
