With Unicode, concerns of running out of space are absurd. There are almost a million unallocated codepoints. At the rate codepoints are being allocated, we won't run out for at least 250 years, and emoji are less than 3% of those allocations. Also, the biggest limitation on the number of codepoints is UTF-16, which we have to pray is dead by the late 2200s (when it dies, we'll have over 2 billion unallocated codepoints.)
