--------------------------------------
Summary: Unable to extract Zip with unknown UniCode path extra
data version
Key: COMPRESS-479
URL: https://issues.apache.org/jira/browse/COMPRESS-479
Project: Commons Compress
Issue Type: Bug
Affects Versions: 1.18
Reporter: Robin Schimpf
Attachments: unicode-test10509149899131946592.zip
The following exception is thrown when the version of the UniCode path extra
data version is not 1. 7-Zip and Windows Explorer will extract the attached
file. The version in the file was changed via a Hex editor to provoke the error.
{code:java}
java.lang.RuntimeException: Error parsing extra fields for entry:
%U20AC_for_Dollar.txt - Unsupported version [116] for UniCode path extra data.

As I understand the specification in Section 4.6.8 and 4.6.9 when the version
is unknown the information shoule be ignored.
Changes MAY NOT be backward compatible so this extra field *SHOULD NOT be used
if the version is not recognized*.
