Description

• 

The IsMonotonic(s) command returns the value true if s is monotonic, and the value false otherwise. A string is monotonic if the sequence of characters it comprises is non-increasing or non-decreasing, when the characters are identified with their ASCII code points.

• 

Every string can be factored into a product (concatenation) of monotonic substrings by using StringTools[MonotonicFactors].

• 

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

• 

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