You seems unaware of why emoji got accepted to Unicode in the first place. Emoji was originated from Japan's three big telcos, which had different sets and encodings of emojis (e.g. some used Shift_JIS extension, some used embedded images via HTML, some used SI/SO sequences). It was already impossible to write a SMS app without accounting for this peculiarity. Unicode thus made this situation much easier, not harder.
