UTF-16 Decoding Algorithm

---

Below is an interactive visualization of the decoding algorithm that takes as input a byte sequence representing a single Unicode character in the UTF-16, UTF-16BE, or UTF-16LE encoding scheme and converts it to the corresponding Unicode code point in hex notation.

Step 1:	Enter a byte sequence for ONE Unicode character in hex notation (for example, D8 12 DC 34 or FFFE3412):
0x
	Pick one of the following encoding schemes:
	UTF-16BE UTF-16LE UTF-16

Step 2:

0x

Step 3:

Step 4:
0x

Step 5:	Finally, add 0x10000 to the hex number above to get the final code point, namely:
U+

Step 3:

The algorithm visualized in this post is described in plain text in this RFC.
