emojize_text.py

"""
Sample script that replaces words with their emoji codes,
if there are any. Depends on the `emoji` module.

"The rabbit is eating a carrot." will be transformed to:
"The 🐇 is eating a 🥕."

Prints on stdout if no OUTPUT_FILE is given.

Usage:
emojize_text.py SOURCE_FILE [OUTPUT_FILE]
