// This file contains test cases with supplementary characters for regular expressions.
// A test case consists of three lines:
// The first line is a pattern used in the test
// The second line is the input to search for the pattern in
// The third line is a concatentation of the match, the number of groups,
// and the contents of the first four subexpressions.
// Empty lines and lines beginning with comment slashes are ignored.
// Test unsetting of backed off groups
