Turn emojis back to punctuation when converting to text

When I enter an emoji :slight_smile: into an Asana task, it helpfully turns it into an image – good. But when it sends that task out in an email, it converts it to:
:slightly_smiling_face:
…Which in perfectly readable, but you know what’s even better? An emoji:
:slight_smile:

When I enter “:)” into an Asana task, it helpfully turns it into a smiling image – good :slight_smile: . But when it sends that task out in an email, it converts it to:
: slightly_smiling_face :
…Which in perfectly readable, but you know what’s even better? An emoji :
