Is the size of C “int” 2 bytes or 4 bytes?
...t the standard unsigned int requires (at least) sixteen bits of storage:
UINT_MAX 65535 // 2¹⁶ - 1
Thus we can see that unsigned int require (at least) 16 bits, which is where you get the two bytes (assuming CHAR_BIT is 8)... and later when that limit increased...

Converting between strings and ArrayBuffers
...; // always utf-8
