> The existing SQLChar datatype has the Derby's default collation which is UCS_BASIC defined
on them. With Derby 10.3, we want to support an additional collation for char datatypes which
will be based on the territory. This jira issue is the placeholder for creating subclass of
SQLChar which will use the passed Collator to do the collation. The current use of this class
in Derby 10.3 will be for territory based collation but this class can be used in future for
other kinds of collations like case-insensitive etc.
