how to convert a string of numbers to a char

Excuse me if this has been answered previously, but I can't seem to find an answer.

How do I convert a string of numbers (e.g "50") into a single char with an ASCII value of the same number, in this case '2'. Is there a way to do this conversion?

Alternatively, could I do the same by converting the string to an int first?

String s = "50";
try {
    char c = (char) Integer.valueOf(s);
    ... c
} catch (NumberFormatException e) {
    ...
}

With catching the NumberFormatException and checking the integer range the code might be made rock-solid.

Here for some languages:

C/C++

int i = 65;
char c = i;
printf("%c", c); // prints A

JS

var c = String.fromCharCode(66);
console.log(c); // prints B

C#/Java

char c = (char)67;
// For Java use System.out.println(c)
Console.WriteLine(c) // prints C

Python

c = chr(68) # for Python 2 use c = str(unichr(68))
print(c) # Prints D
