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

Dear Mikael,
 
thanks for the kind words. :-)
 
I should add that TrueZIP uses CP437 for all files ending with a .ZIP suffix
by default (this is configurable). However, for this to work, a user must
have a *full* installation of the JRE. The standard installation
unfortunately does not come with CP437, in which case TrueZIP automatically
reverts to UTF-8, unfortunately without a trace yet. I will document or
enhance this somewhat later (probably reverting to CP850 instead if this is
a close match to CP437 and available in any standard JRE installation).
 
On the random access: Like the java.util.zip.ZipFile class, TrueZIP does
provide random access to individual entries of a ZIP file without
decompressing the entire archive. However, due to the ZIP deflation
algorithm, it is impossible to randomly access/seek the contents of a
compressed ZIP file entry. Thus, contents must always be streamed for
compression/decompression and hence TrueZIP provides drop-in replacements
for FileInputStream and FileOutputStream, but not for RandomAccessFile.
Again, I will add this to an FAQ on a later version.
 
On RAR: Unfortunately no. I don't think its in widespread use anymore -
please correct me from wrong.
 
With best regards,
Christian
