说明
iconv converts text files from one character encoding to another. It reads input in the source encoding and writes output in the target encoding, handling the character mapping between different character sets. The tool supports hundreds of encodings including UTF-8, ISO-8859 family, Windows code pages, Asian encodings, and legacy formats. Special suffixes //TRANSLIT (approximate conversion) and //IGNORE (skip unconvertible) modify conversion behavior. iconv is essential for handling files from different systems, migrating legacy data, and ensuring proper text display across platforms with different default encodings.
