Starting with %E3%82%AB. Let me convert each of these sequences to ASCII.

Alternatively, perhaps the correct approach is to input the entire sequence into a UTF-8 decoder. Let me check the entire string: Starting with %E3%82%AB

Code point = (((first byte & 0x0F) << 12) | ((second byte & 0x3F) << 6) | (third byte & 0x3F)) Let me check the entire string: Code point

Wait, first byte is E3 (hex), which is 227 in decimal. The UTF-8 three-byte sequence for code points in U+0800 to U+FFFF starts with 1110xxxx, and the code point is calculated as ((first byte & 0x0F) << 12) | ((second byte & 0x3F) << 6) | (third byte & 0x3F). Hmm, I might be making a mistake here

Looking up U+B2AB... Hmm, I might be making a mistake here. Alternatively, perhaps it's easier to just use a UTF-8 decoder tool. Let me try decoding the sequence E3 82 AB.

Let me use an online decoder or write out the steps. Let's take each %E3, %82, %AA, %E3, etc., decode each pair, and then combine the hex bytes.

E3 in hex is 227, 82 is 130, AB is 171. So the bytes are 0xEB, 0x82, 0xAB. In UTF-8, three-byte sequences are for code points from U+0800 to U+FFFF. The first three bytes for "カ" (k katakana ka) should be 0xE381AB? Wait, maybe I need to refer to a Japanese encoding table.
