<para>
This class is provided because Unicode contains large number of characters
and incorporates the varied writing systems of the world and their incorrect
usage can expose programs or systems to possible security attacks using
characters similarity.
</para>
<para>
Provided methods allow to check whether an individual string is likely an attempt
at confusing the reader (<literal>spoof detection</literal>), such as "pаypаl"
spelled with Cyrillic 'а' characters.
