Info-ZIP Unicode Path Extra Field (0x7075): ==========================================.
Stores the UTF-8 version of the file name field as stored in the local header and central directory header. (Last Revision 20070912)
Value Size Description
(UPath) 0x7075 Short tag for this extra block type ("up") TSize Short total data size for this block Version 1 byte version of this extra field, currently 1 NameCRC32 4 bytes File Name Field CRC32 Checksum UnicodeName Variable UTF-8 version of the entry File Name
Currently Version is set to the number 1. If there is a need to change this field, the version will be incremented. Changes may not be backward compatible so this extra field should not be used if the version is not recognized.
The NameCRC32 is the standard zip CRC32 checksum of the File Name field in the header. This is used to verify that the header File Name field has not changed since the Unicode Path extra field was created. This can happen if a utility renames the File Name but does not update the UTF-8 path extra field. If the CRC check fails, this UTF-8 Path Extra Field should be ignored and the File Name field in the header should be used instead.
The UnicodeName is the UTF-8 version of the contents of the File Name field in the header. As UnicodeName is defined to be UTF-8, no UTF-8 byte order mark (BOM) is used. The length of this field is determined by subtracting the size of the previous fields from TSize. If both the File Name and Comment fields are UTF-8, the new General Purpose Bit Flag, bit 11 (Language encoding flag (EFS)), can be used to indicate that both the header File Name and Comment fields are UTF-8 and, in this case, the Unicode Path and Unicode Comment extra fields are not needed and should not be created. Note that, for backward compatibility, bit 11 should only be used if the native character set of the paths and comments being zipped up are already in UTF-8. It is expected that the same file name storage method, either general purpose bit 11 or extra fields, be used in both the Local and Central Directory Header for a file.
