Disabling auto- emoticons/emoji/smiley in OSX 10.9 Mavericks for Messages app

Here's a thing that bugged my since upgrading to OSX 10.9 Mavericks: The messages app kept changing regular ascii-emoticons such as ":)" to the build-in icon type emoticons known from iOS...

Since searching the web didn't produce results from OSX 10.9 Mavericks I had to figure it out myself. There is no way to change this in settings, and the way it was done in OSX 10.8 Mountain Lion (right click the conversation area and choose "Show Smileys)" was not available.

The simple way to disable the auto-emoticons is to right click in the text input area, select Substitutions and click on "Emoji" (or "Text Replacement" in general if you do not like that).

The screenshot shows where to locate the option.
