Bug 1339331 TextEventDispatcher should replace \r in composition string with \n and TextComposition should allow to input \n with composition events r=m_kato According to ATOK's behavior, IME may send different line breaker from its platform's standard. Therefore, we should treat \r as \n too. Additionally, currently, TextComposition doesn't allow to input \n with composition. However, this was added for preventing to see odd control characters as boxes with code point. Therefore, we should allow \n for IMEs. (It was allowed, this limitation is unexpected when I reviewed the patch to reject control characters in TextComposition.) MozReview-Commit-ID: DzGSMgp89Av
