This is the fundamental difference between the ASCII emoji and the pictogram emoji's.
The ASCII emoji's were a shorthand form of adding emotion to a text and were few and defined, so that it was relatively easy to remember or look up one you didn't know - either to know what it meant but also to see if there was an emoji that conveyed the emotion you wanted to express.
With the pictogram emoji's there seems to be no such reference. My Andriod phone simply displays lots of pictograms, but without any indication of what they might mean; so giving ambiguity to pictogram emoji's.
