 *  PKZIP for Windows 2.5, 2.6, and 4.0 flag their entries as "FS_FAT_", but
 *  the filename stored in the local header is coded in Windows ANSI (CP 1252
 *  resp. ISO 8859-1 on US and western Europe locale settings).
 *  Likewise, PKZIP for UNIX 2.51 flags its entries as "FS_FAT_", but the
 *  filenames stored in BOTH the local and the central header are coded
 *  in the local system's codepage (usually ANSI codings like ISO 8859-1).
 *
 * All other ports are assumed to code zip entry filenames in ISO 8859-1.
