In all Mac OS encodings, character codes 0x00-0x7F are
identical to ASCII, except that
  - in Mac OS Japanese, yen sign replaces reverse solidus
  - in Mac OS Arabic, Farsi, and Hebrew, some of the
    punctuation in this range is treated as having strong
    left-right directionality, although the corresponding
    Unicode characters have neutral directionality
So, for best compatibility, confine filenames to the standard
7-bit ASCII character set.

If you generate a filename list of your archive (unzip -l),
you will see the converted filenames. Your can also extract
the archive with the switch '-i' (= ignore mac filenames),
and test your result.

This MacZip port uses its own filename stored in the
archive. At the moment, the filename will be not converted.
However, I'm planning to add support for Unicode.

Currently, the following Mac OS encodings are NOT supported:
Japanese, ChineseTrad, Korean, Arabic, Hebrew, Greek,
Cyrillic, Devanagari, Gurmukhi, Gujarati, Oriya, Bengali,
Tamil, Telugu Kannada, Malayalam, Sinhalese, Burmese, Khmer,
Thai, Laotian, Georgian, Armenian, ChineseSimp, Tibetan,
Mongolian, Ethiopic, Vietnamese, ExtArabic and finally:
Symbol - this is the encoding for the font named "Symbol".
Dingbats - this is the encoding for the font named "Zapf Dingbats".
If you extract an archive coded with one of these
charsets you will probably get filenames with funny
characters.

These problems apply only to filenames and NOT to the file
content.
of course: The content of the files will NEVER be converted !!



File-/Creator Type:
-------------

This port uses the creator type 'IZip' and it is registered
at Apple (since 08. March 1998). File types can not be
registered any more. This port uses 'ZIP ' for Zip archive
files. The creator 'IZip' type should be used for all future
versions of MacZip.



Hints for proper restoration of file-time stamps:
-------------------------------------------------

UnZip requires the host computer to have proper time zone
information in order to handle certain tasks correctly (see
unzip.txt).  To set the time zone on the Macintosh, go to
the Map Control Panel and enter the correct number of hours
(and, in a few locales, minutes) offset from Universal
Time/Greenwich Mean Time.  For example, the US Pacific time
zone is -8 hours from UTC/GMT during standard (winter) time
and -7 hours from UTC/GMT during Daylight Savings Time.  The
US Eastern time zone is -5 hours during the winter and -4
hours during the summer.

Discussion of Daylight Savings Time
-----------------------------------
The setting in the Date & Time control panel for Daylight
Savings time is a universal setting. That is, it assumes
everybody in the world is observing Daylight Savings time
when its check box is selected.

If other areas of the world are not observing Daylight
Savings time when the check box is selected in the Date &
Time control panel, then the Map control panel will be off
by an hour for all areas that are not recognizing Daylight
Savings time.

Conversely, if you set the Map control panel to an area that
does not observe Daylight Savings time and deselect/uncheck
the check box for Daylight Savings time in the Date & Time
control panel, then time in all areas celebrating Daylight
Savings time will be off by an hour in the Map control
panel.

Example:
     In the case of Hawaiians, sometimes they are three hours
     behind Pacific Standard Time (PST) and sometimes two hours
     behind Pacific Daylight Time (PDT). The Map control panel
     can only calculate differences between time zones relative
     to Greenwich Mean Time (GMT). Hawaii will always show up as
     three hours past the Pacific time zone and five hours past
     the Central time zone.

     When Hawaiians are not observing Daylight Savings time, but
     the rest of the country is, there is no combination of
     settings in Map and Date & Time control panels which will
     enable you to display Hawaiian local time correctly AND
     concurrently display the correct time in other places that
     do observe Daylight Savings time.

     The knowledge about which countries observe Daylight Savings
     time and which do not is not built into the Map control
     panel, so it does not allow for such a complex calculation.

     This same situation also occurs in other parts of the world
     besides Hawaii. Phoenix, Arizona is an example of an area of
     the U.S. which also does not observe Daylight Savings time.

Conclusion:
MacZip only knows the GMT and DST offsets of the
current time, not for the time in question.
