Alternatively, perhaps the correct approach is to input the entire sequence into a UTF-8 decoder. Let me check the entire string:

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. Alternatively, perhaps the correct approach is to input

Wait, E3 is 0xEB in hex, but we are considering each % as a byte. So the sequence is E3 82 AB. Wait, E3 is 0xEB in hex, but we

So first byte is E3 (binary 11100011), so & 0x0F is 0x0B. Second byte is 82 (10000010) → & 0x3F is 0x02. Third byte is AB (10101011) → & 0x3F is 0xAB? Wait, AB is 0xAB, which is 10 in hexadecimal. But 0xAB is 171 in decimal. Wait, but 0xAB is 171. Second byte is 82 (10000010) → & 0x3F is 0x02

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.

%AB%E3%83%AA → Wait, after decoding %E3%82%AB: E3 82 AB is "カ" (ka). Then %E3%83%AA is E3 83 B2 (since %83%AA would be 83 AA?), wait maybe I made a mistake here. Let's go step by step.
