% eliminated part of local minizip patch by using
newer API flavor and passing version_made_by value
in interface code.
* contrib/hbmzip/mzip.c
% use sizeof() instead of repeating HB_PATH_MAX
+ use larger than HB_PATH_MAX buffer to read out
filenames stored in zip file entries. (useful when
using unicode filenames which are stored in UTF-8)
+ added support for .zip unicode filename and comment
support introduced in PKZIP 6.3.2 [dated 2007] standard:
[http://www.pkware.com/documents/casestudies/APPNOTE.TXT]
hb_zipFileCreate()/hb_zipStoreFile()/hb_zipStoreFileHandle()
will now accept a new last parameter <lUnicode>,
which when .T. will force to store the filename/comment
in UTF8 in the .zip file.
hb_unzipFileInfo()/hb_unzipExtractCurrentFile()
will now honor filenames/comments stored in unicode
mode and make any necessary conversions.
; Notice that not every .zip tool support this relatively
new PKZIP format extension. Also notice that before that
extension the only officially supported codepage was
CP437 [See D.1 in Appendix D], which means no accented
chars. Whatever else CP used, the behavior becomes
application dependent and may or may not work as expected.
; Test/review/whatever
* contrib/hbmzip/tests/myunzip.prg
+ standardized date format
+ switched internally to unicode to be able to handle
unicode code to work best with unicode zips.
* contrib/hbmzip/tests/myzip.prg
+ new '--unicode' switch to enable storing filenames
in unicode by using PKZIP 6.3 .zip format and
unicode mode internally.
