Lightning Talk: Encoding - Understanding the Basics
summary
A concrete bug from the vault squad at spread Li motivates a short history and three practical rules: encoding is a reversible mapping not encryption, misdetecting a file's encoding can cause permanent data loss, and today UTF-8 dominates 93.3% of web pages so use it and prefer UTF‑8-capable tools. The talk demonstrates ASCII → multibyte → Unicode evolution, shows UTF-8’s byte-width tradeoffs, and insists on declaring and parsing encodings rather than guessing.
