https://bugs.webkit.org/show_bug.cgi?id=103295 Reviewed by Brent Fulgham. Source/WebCore: Changed TextIterator to use the contained string instead of calling characters() on that string. Other sources of text, like emitCharacter() still use the contained UChar* buffer. Added appendTextToStringBuilder() to append the text contents of the current iterator to a string builder irrespective of the source of the text. No new tests as functionality covered by existing tests. * WebCore.exp.in: Updated plainText export and eliminated plainTextToMallocAllocatedBuffer export * accessibility/AccessibilityObject.cpp: (WebCore::AccessibilityObject::stringForVisiblePositionRange): Updated to use TextIterator::appendTextToStringBuilder() * editing/TextIterator.cpp: (WebCore::TextIterator::characterAt): New function to return the indexed character of the current TextIterator (WebCore::TextIterator::appendTextToStringBuilder): Added method to append whatever the current text to a StringBuilder (WebCore::TextIterator::emitText): Eliminated accessing the character data via characters(). (WebCore::TextIterator::rangeFromLocationAndLength): Changed to use characterAt(). (WebCore::plainText): Combined with plainTextToMallocAllocatedBuffer(). * editing/TextIterator.h: (WebCore::TextIterator::startOffset): New getter. (WebCore::TextIterator::string): New getter. (WebCore::TextIterator::characters): Updated to use correct test source. * page/ContextMenuController.cpp: (WebCore::selectionContainsPossibleWord): Changed to use characterAt(). Source/WebKit/mac: Updated _stringForRange to use plainText() instead of removed plainTextToMallocAllocatedBuffer(). * WebView/WebFrame.mm: (-[WebFrame _stringForRange:]): git-svn-id: http://svn.webkit.org/repository/webkit/trunk@135972 268f45cc-cd09-0410-ab3c-d52691b4dbfc
