Determines the character representation for a specific digit in the specified radix.

<p class="para">
If the value of radix is not a valid radix, or the value of digit is not a valid digit in the specified radix,
the null character (<em>U+0000</em>) is returned.

<p class="para">
The radix argument is valid if it is greater than or equal to <em>2</em> and less than or equal to <em>36</em>.
The digit argument is valid if <em>0 <= digit < radix</em>.

If the digit is less than <em>10</em>, then '0' + digit is returned. Otherwise, the value 'a' + digit - 10 is returned.
