The IsAnagram(s,t) command returns the value true if the string s is an anagram (permutation) of the string t. Otherwise, the value false is returned.

If s and t are empty strings, 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.
