HTC One - Upgrade to 4.3 - new default emoticons

[Steven Oliver1974]

My HTC One did a download and upgrade to 4.3 yesterday (Sunday). As a result it now has new Emoji emoticons which don't show in past messages. I have Handcent SMS which does uses the previous emoticons and also the Emoji ones, and allows to you swap. No such luxury on the default messaging app though! Is there any way of getting the Emoji emoticons changed on the standard application or am I saddled with them from now on?
