Abstract

A practical rundown of the classic failure patterns in business-app CSV I/O - hand-rolled Split(',') parsing, mojibake from BOM-less UTF-8 in Excel, lost leading zeros, and CSV injection - covering RFC 4180's rules, handling Shift_JIS in .NET (CodePagesEncodingProvider), and safe reading with TextFieldParser.
