UTF-32 sandbox (decode)

Convert 4 UTF-32 bytes into a Unicode code point, given the endianness.

Bytes

Hex (with or without 0x). UTF-32 takes exactly 4 bytes per code point.

Step-by-step breakdown

01
Given endianness
The 4 bytes are read low-order byte first (Little Endian). Mentally reverse the byte order before assembling the number.
Little Endian (LE)
02
Reassemble the binary
Concatenate the 4 bytes (reordered as Big Endian) to reform the full 32-bit binary.
In UTF-32 this binary IS the code point - no marker to strip, no surrogate to recombine.

03
Convert to a code point
The binary equals 127881 in decimal, i.e. U+1F389 in Unicode notation.
