-  virtual bool check_partition_func_processor(byte *bool_arg) { return FALSE; }
+
+    The general behaviour is that most integer functions are allowed.
+    If the partition function contains any multi-byte collations then
+    the function check_part_func_fields will report an error on the
+    partition function independent of what functions are used. So the
+    only character sets allowed are single character collation and
+    even for those only a limited set of functions are allowed. The
+    problem with multi-byte collations is that almost every string
+    function has the ability to change things such that two strings
+    that are equal will not be equal after manipulated by a string
+    function. E.g. two strings one contains a double s, there is a
+    special german character that is equal to two s. Now assume a
+    string function removes one character at this place, then in
+    one the double s will be removed and in the other there will
+    still be one s remaining and the strings are no longer equal
+    and thus the partition function will not sort equal strings into
+    the same partitions.
+
+    So the check if a partition function is valid is two steps. First
+    check that the field types are valid, next check that the partition
+    function is valid. The current set of partition functions valid
+    assumes that there are no multi-byte collations amongst the partition
+    fields.
