IBM Watson dialog emoji inputs

Does the Dialog service support emoji inputs?

I was able to output emojis using both: HTML Entity (decimal)  HTML Entity (hex)  http://www.fileformat.info/info/unicode/char/1f37b/index.htm

However, I can't get the dialog service to understand emoji inputs. Emojis in dialog conversation

You most certainly can. Here’s an example:

<?xml version="1.0" encoding="UTF-8" ?>
<dialog xsi:noNamespaceSchemaLocation="WatsonDialogDocument_1.0.xsd"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<flow>
<folder label="Main">

Output an initial prompt:

  <output>
    <prompt>
      <item>Write something and I’ll echo it back to you.</item>
    </prompt>
  </output>

Get input:

  <getUserInput>
    <input>
      <grammar>
        <item>(ANYTHING)={anything}</item>
      </grammar>
      <action varName="anything" operator="SET_TO">{anything.source}</action>
      <output>
        <prompt>
          <item>{anything}</item>
        </prompt>
      </output>
    </input>
  </getUserInput>

</folder>
</flow>

Now, I guess you have tried to capture inputs the way IBM does it in all its examples. But that method silently drops many non-ASCII characters. It’s just not how you want to capture inputs. (See this SO answer for a list of some of the characters it drops.)

Here’s how I do it:

<entities>
  <entity name="ANYTHING">
    <value>
      <grammar>
        <item>!.*</item>
      </grammar>
    </value>
  </entity>
</entities>

The exclamation point means that we’re using a regular expression. (Everything after ! is the regex.) This method does not drop as many characters, but it will drop < and >. Possibly others. You can use this same script to find out which characters are safe.

And finally we’ll need the variable to capture into.

<variables>
  <var_folder name="Home">
    <var name="anything" type="TEXT" />
  </var_folder>
</variables>

</dialog>

See this gist for the complete example.
