Lucky 7 - Designing Text Encodings for C++
summary
Proposes a minimal encoding object with exactly seven elements — lucky seven — (code_point, code_unit, state, max_code_points, max_code_units, encode_one/decode_one, plus result types) and shows it composes whole APIs: streaming ranges, validation, counting, and transcoding by a simple decode-then-encode loop. Demonstrates real numbers: UTF‑8 expands up to max code units 4, EBCDIC example uses max 6, and std::text helpers (encode/validate/transcode) implement the loop safely with error handling.
