Inspecting Non-UTF-8 ZIP File Names CLI: Solution
When working with ZIP files, you may encounter file names that are not UTF-8 encoded. While GUI archive managers can display and extract these files without issues, programmatically obtaining the binary representation of such file names can be challenging.
Understanding the Problem
ZIP files use a specific format to store file information, including file names. When file names are not UTF-8 encoded, they can cause issues when reading or extracting files programmatically. This issue is common when dealing with legacy systems or files from non-Unicode environments.
Finding a Solution
To address this problem, you can use a command-line interface (CLI) tool that can handle non-UTF-8 encoded file names in ZIP files. One such tool is unzip.
Using unzip
unzip is a command-line tool that can extract files from ZIP archives. By default, it uses the system's locale settings to decode file names. However, you can override this behavior and force it to use a specific encoding, such as the ZIP file's default encoding.
Example
The following command extracts a file named éàèìòù.txt from a ZIP archive, even if the file name is not UTF-8 encoded:
In this example, -O cp437 specifies the code page to use for decoding file names. You can replace cp437 with the appropriate code page for your ZIP file.

By using the unzip command-line tool with the appropriate code page, you can programmatically extract files from ZIP archives, even if the file names are not UTF-8 encoded. This solution is platform-independent and can be used in any environment where unzip is available.
