As Harald said, it would be good to test with a commercial core network, but I don't have one :)
I don't know if this helps, but I got curious and sent the 40-emoji-message from a phone connected to a commercial network and captured it via SS7. (So no Osmocom involved.)
The pcap file is attached (addresses removed).
It looks like the 4-byte characters don't get split in half, but the last two bytes get pushed to the next message, and all emojis are received unharmed.
One thing I don't get though: where is it even specified that you can use UTF-16 in SMS? Even the latest 23.038 only lists UCS-2.
