RE: [Jazzlib-developers] [bug] Jazzlib and codepages

Dear Christian,
 

in fact, CP437 should be used.
[Mikael Bourges-Sevenier] 
Great, thanks! 
 
However, there's been a long discussion about this and the outcome is that
jazzlib's objective is to provide as much compatibility to the J2SE API as
possible. This means in this case that UTF-8 must be used because Sun has
once decided to do so - this is a well known bug by the way.
[Mikael Bourges-Sevenier] 
Yes before using this library, I made some research on the web and I was
really surprised to see that this bug hasn't been resolved for so many
years! Somehow, this doesn't surpise me too much as many codecs/parsers are
not optimized or very limited in core java libraries.
 
If you would like to try another library which addresses this (and many
other) restrictions of the genuine java.util.zip package, then please have a
look at my TrueZIP project at  <http://truezip.dev.java.net>
http://truezip.dev.java.net . Its low level API is backwards compatible to
java.util.zip and provides many extensions like a selectable character
encoding and the high level API makes working with ZIP files redundant by
providing a drop-in replacement for the classes File, FileInputStream,
FileOutputStream and others which treat ZIP files like directories in the
pathname (a virtual ZIP file system).
[Mikael Bourges-Sevenier] 
I was unaware of your library. This is exactly what I needed, thanks. I'm
going to try it right now!
 
In fact, I don't care much about compliance with java.util.zip package but I
do care about compliance with zip format and other zip programs such as
winzip.
 
In my applications, I need to access files within an archive in a very fast
manner. In general, the archive is not decompressed, only random items
within. I wonder if NIO's file mapping could be used instead of streams and
if it might be faster for such random accesses? 
 
Last, but not least, I'm looking for a RAR reader. Is there a TrueRar out
there?
 
Kind regards,
 
Mike

Subject: [Jazzlib-developers] [bug] Jazzlib and codepages


Dear All,
 
In ZipFile.java and ZipInputStream.java, there is a bug when reading file
names. On WinXP, one must use codepage Cp850 (PC Latin-1 codepage).
 
So you should replace:
    String name = new String(buffer);
by
    String name = new String(buffer,"Cp850");
 
However, I wonder if there is any indication in the zip spec about the
codepage used to encode filename so it would be more generic than using
Cp850.
 
How does it sound?
 
Kind regards,
 
Mike
