Why do some platforms count bytes instead of characters?

Platforms like Amazon and eBay count bytes (UTF-8 encoding) for certain fields because Asian characters (Chinese, Japanese, Korean) take 3 bytes each. A 200-byte limit may only allow ~66 Chinese characters.

Why does Amazon count bytes instead of characters?

Amazon uses UTF-8 encoding for backend search terms. Chinese, Japanese, and Korean characters take 3 bytes each, while English characters take 1 byte. A 250-byte limit means only ~83 CJK characters.

What is the Amazon title character limit?

Amazon allows up to 200 characters for most categories. However, only 70-80 characters are visible on mobile devices, so keep the most important keywords at the beginning.

How many bullet points can I have on Amazon?

Amazon allows 5 bullet points, each with a maximum of 500 characters. The first few words should highlight the key feature.
