// Description:
// e32test\buffer\t_match.cpp
// Overview:
// Test the match methods of TPtrC8 and TPtrC16 objects and the 
// TCharIterator TCombiningCharIterator, TCollationValueIterator
// and TCollationRawValueIterator classes.
// API Information:
// TPtrC8, TPtrC16, TCharIterator, TCombiningCharIterator,
// TCollationValueIterator, TCollationRawValueIterator
// Details:
// - Test and verify the results of TPtrC8 Match and MatchF methods
// on a variety of constant strings. Verify both match and mismatch
// conditions.
// - Test and verify the results of TPtrC16 Match and MatchF methods
// on a variety of constant strings. Verify both match and mismatch
// conditions.
// - For a TCharIterator object, test and verify:
// - basic character handling
// - ability to reset the iterator correctly
// - combining characters works as expected
// - ability to jump into the middle of combined characters
// - full-width variants are not modified
// - narrow strings work as expected
// - surrogate pairs work as expected
// - Using a TCombiningCharIterator object with a variety of character 
// strings as input, verify that the output is as expected.
// - Using TCollationValueIterator and TCollationRawValueIterator objects:
// - test the raw iterator 
// - test starting at different points in the iteration and verify capitals 
// are ignored at level 0
// - verify capitals are ignored at level 1
// - verify capitals do not match at level 2
// - check the TCollationValueIterator Restart method
// - test collation keys, when they success and when they fail halfway
// - exhaust the internal cache, verify object still works
// - test different decompositions at level 3
// - verify results are as expected
// - Test and verify the results of the TUnicodeFold::FindWildcardMatchFolded()
// method on a variety of constant strings: find a string within another 
// string, verify the offset into the candidate string if it is present, or 
// KErrNotFound if it is not.
// - Test and verify the results of the TUnicodeFold::FindFolded() method on 
// a variety of constant strings: compare two strings, verify return value.
// - Test and verify results of UnicodeFoldCase() on a variety of characters.
// - Test and verify results of MatchLeadingWildcards() on a variety of strings.
// - Test and verify results of MatchesHereFoldedWithPrefixTest() on a variety 
// of strings.
// - Test and verify results of LocateFolded() on a variety of strings.
// - Test and verify results of FindFoldedWithWildcard() and FindMatchFolded()
// on a variety of strings.
// - Test and verify results of TDesc.CompareF() on a variety of strings.
