+/**
+* 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
