"%E3%82%AB%E3%83%AA%E3%83%93%E3%82%A1%E3%83%B3%E3%82%B3%E3%83%A0 062212-055"

First segment: %E3%82%AB: E3 82 AB → Decode in UTF-8. Let's do this properly.

Code point = (((first byte & 0x0F) << 12) | ((second byte & 0x3F) << 6) | (third byte & 0x3F))

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

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