No. You can't put more than 70 16-bit unicode characters into a
single SMS, because the SMS User Data (UD) field is limited to
140 bytes (octets).

You could send 140 unicode characters as a concatenated message
in PDU-mode. But given the required numbering and indexing
overheads then eroding the available UD space, you'd need a
3-part concatenated message to hold that text. This would
appear as 3 individual SMSs to the radio layer (and be charged
as such), but should appear as a single message to a modern
receiving handset.

It would also require you to code up 3 individual PDUs.
