About this file
A CSV for testing character-encoding detection and conversion. It contains Japanese names and addresses, so it exercises the same conditions as real business data.
Mojibake happens only when the encoding the reader assumes differs from the file's actual encoding. UTF-8 with and without a BOM behave differently in Excel, and Shift_JIS versus CP932 differ in how they treat vendor-specific characters such as circled numerals and Roman numerals. Run all four variants and check you get identical results.
