How to Become an Encoding Champion
summary
Explains why encoding causes real bugs and how to fix them: Ruby’s encode vs force_encoding distinction (encode rewrites bytes irreversibly, force_encoding only reinterprets) solves the author’s bug where a response arrived as ASCII-8BIT despite a UTF-8 request; shows using bytesize, bytes, ord and chr to inspect data; cites UTF-8 adoption >94% of pages and Unicode 137,929 characters (May 2019); covers Base64 behavior: encode64 inserts linefeeds every 60 chars unless strict is used and strict_decode raises an error.
