How to troubleshoot an error "cannot be compressed because it includes characters that cannot be used in a compressed folder."

Windows 11 offers its users a function "Compress to ZIP file" in the context menu of File Explorer.

You may use other third-party archiving software compatible with Unicode filenames to compress a file whose name includes such less common characters. Bandizip is fully compatible with Unicode (UTF-8) filenames in the ZIP format.
