------- Comment #5 from ap at webkit.org  2009-03-04 03:35 PDT -------
+    // For example, we should not insert a character break after a Thai
preposed
+    // character (a Thai vowel character) because it breaks a syllable.
+    // On the other hand, we should be able to move an input cursor even after
+    // a Thai preposed character.

Where should the former character break iterator come into play? Should we
allow selections that only cover a prepend character, for example?

I'd like to have as many examples of use cases for either iterator as possible,
to avoid future confusion.

What about my AtomicString comment? I still don't think that you need atomic
strings here. The reason for them to exist is quick comparison - two
AtomicStrings are equal if and only if their impl pointers are equal.

+    // The only difference from the original rules is:
+    //   added "!!chain" to change this rule set to chained.

Please expand this comment to explain why we need to make the rule set chained.
