[Building Sakai] [Assignment tool ] Zip upload/download does not format special character properly

[Cyril Mace]

Hello,

On our Sakai 2.8.1 instance we were having problems with Download 
All/Upload All feature of Assignment tool when using special characters.

For example:

1) A student submit an assignment including a file named 
/*mon_résultat.txt*//
/2) The instructor  downloads all the submissions of the assignment => 
the file name will be changed to /*mon_r*//*e*//*sultat.txt*/ within the 
bulk_download.zip archive.
3) The instructor update the content of the comment.txt file and write a 
comment with special characters (éééééé), then zip it to use the "Upload 
All" feature => the ééé are replaced by ??????characters in the comments 
area.

Has anyone experienced this problem?
We solved it by using the /*org.apache.tools.zip*/ library instead of 
the native/*java.util.zip*/ one and are thinking about doing the same 
for our 2.9.1 instance.
We could make the use of the apache library configurable through a sakai 
property and submit a patch if needed.

Thanks for reading,
