These functions check whether a character or string
falls into a certain character class according to the i
current locale.
</para>
<para>
When called with an integer argument these functions
behave exactly like their C counterparts.

When called with a string argument they will check
every character in the string and will only return
true if every character in the string matches the
requested criteria.
</para>

Passing anything else but a string or integer will
return false immediately.
