The IsPalindrome(s) command returns the value true if s is a palindrome, and the value false otherwise. A palindrome is a string s that is equal to its reverse: $s=\mathrm{Reverse}\left(s\right)$.

If s is the empty string, the command returns true.

All of the StringTools package commands treat strings as (null-terminated) sequences of $8$-bit (ASCII) characters.  Thus, there is no support for multibyte character encodings, such as unicode encodings.
