- Strips entities and non-word characters (spaces, tabs, newlines, carriage returns, punctuation symbols)
- Replaces any remaining HTML entities with their appropriate character
- Uses crypt() to encrypt the words if $encrypt is true
- $max_chars is the maximum number of characters each word should be
- If $encrypt is true, the returned array will contain integers that can be used to figure out what each word was
- If $encrypt is false, the returned array will simply contain all the words that were inserted
