FD-2026-014 Encoding mismatch (claims UTF-8, sends Latin-1)

corruption moderate encodingcharset

Anatomy

Content-Type says UTF-8; the bytes are Latin-1. "café" and "São Paulo" arrive with 0xE9/0xE3 codepoints that are invalid UTF-8. Java's String decoders throw or mojibake; Go accepts the bytes silently and corrupts downstream indexes. The classic enterprise- system export failure.
