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.

First segment: %E3%82%AB: E3 82 AB → Decode in UTF-8. Let's do this properly. E3 in hex is 227, 82 is 130, AB is 171

Looking up Unicode code point U+B2AB... Hmm, that's not right. Wait, perhaps I made an error in the calculation. Let me recheck. E3 in hex is 227
