%e3%82%ab%e3%83%aa%e3%83%93%e3%82%a2%e3%83%b3%e3%82%b3%e3%83%a0 062212-055 -

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

Each %E3%82%AB is a three-byte sequence: Starting with %E3%82%AB

The numbers "062212-055" could be a product code, like a part number, serial number, or ISBN. The first part 062212 might be a date, like June 22, 2012, but not sure. The user says "article", but the term might refer to an article in a publication, or an article (item) in a store. Alternatively, it could be a model number. The first part 062212 might be a date,

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

So the first part is E3 82 AB. Let me convert these bytes from hexadecimal to binary. E3 is 11100011, 82 is 10000010, AB is 10101011. In UTF-8, these three bytes form a three-byte sequence. The first byte starts with 1110, indicating it's part of a three-byte sequence. The next two bytes start with 10, which are continuation bytes.

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.

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.
