ArchiveInputStream#getNextEntry(): Problems with WinZip directories with Umlauts
--------------------------------------------------------------------------------
Key: COMPRESS-176
URL: https://issues.apache.org/jira/browse/COMPRESS-176
Project: Commons Compress
Issue Type: Bug
Components: Archivers
Affects Versions: 1.3
Environment: Windows 7
Reporter: Wurstbrot mit Senf
There is a problem when handling a WinZip-created zip with Umlauts in
directories.
I'm accessing a zip file created with WinZip containing a directory with an
umlaut ("รค") with ArchiveInputStream. When creating the zip file the
unicode-flag of winzip had been active.
The following problem occurs when accessing the entries of the zip:
the ArchiveEntry for a directory containing an umlaut is not marked as a
directory and the file names for the directory and all files contained in that
directory contain backslashes instead of slashes (i.e. completely different to
all other files in directories with no umlaut in their path).
There is no difference when letting the ArchiveStreamFactory decide which
ArchiveInputStream to create or when using the ZipArchiveInputStream
constructor with the correct encoding (I've tried different encodings CP437,
CP850, ISO-8859-15, but still the problem persisted).
This problem does not occur when using the very same zip file but compressed by
7zip or the built-in Windows 7 zip functionality.
