/**
* UTF-8 aware alternative to substr
* Return part of a string given character offset (and optionally length)
*
* Note arguments: comparied to substr - if offset or length are
* not integers, this version will not complain but rather massages them
* into an integer.
*
* Note on returned values: substr documentation states false can be
* returned in some cases (e.g. offset > string length)
* mb_substr never returns false, it will return an empty string instead.
* This adopts the mb_substr approach
*
* Note on implementation: PCRE only supports repetitions of less than
* 65536, in order to accept up to MAXINT values for offset and length,
* we'll repeat a group of 65535 characters when needed.
*
* Note on implementation: calculating the number of characters in the
* string is a relatively expensive operation, so we only carry it out when
* necessary. It isn't necessary for +ve offsets and no specified length
