zlib.ZipEntry.name

The entry's name, decoded from the central directory, which is treated as authoritative - a local file header that disagrees is ignored, so a mismatched-header ("ZIP-confusion") archive cannot make name disagree with what is read. The bytes are decoded from a valid Info-ZIP Unicode Path extra field (0x7075) when one is present; otherwise as UTF-8 when the language-encoding flag (general-purpose bit 11) is set or the bytes are valid UTF-8 (plenty of tools wrote UTF-8 names without ever setting the flag); and as CP437 - the historical default - only when they are not. See zipEntry.nameBuffer for the raw bytes.

The name is returned verbatim: it is never normalized, and a name containing .., a leading /, a drive letter, or backslashes is neither rewritten nor rejected. A ZipFile/ZipBuffer never writes to disk, so guarding against path traversal ("Zip Slip") when extracting is the caller's responsibility.
