ZFS incompatibility: Filenames UTF8, formC /D ?

Post by jollyjinx » Thu Dec 20, 2012 8:54 am

Hello all,

i'm using ZEVO for almost a year and never have had problems with filenames. Now I got a zip file from a Windows user that I could not unzip (on ZFS). I clicked on it in Finder and it told me that it was unable to expand the file ( "Unable to finish expanding" ). Looking at the console I saw nothing. I wondered if it might be a ZFS problem and expanded the file on HFS+ and it worked.

So it's the first time that I've encountered an incompatibility with ZFS.

I've created a pool with option -o normalisation=formC and there I was able to uncompress the file in Finder.

I now wonder if formC is maybe better beeing used instead of the default formD ?

What file name seemed problematic with form D?

Recalling a previous topic – NFD: normalization=formD (normalisation form D) – I assume that for the majority of use cases, form D is is preferred on OS X.

Please, can you easily identify the name of the file that seemed problematic with formD?

Was the failed expansion with Apple's default Archive Utility?

It was a Filename wit a German Umlaut a (ä) generated on a German Windows system. I tried creating a zipfile myself , but I only have access to a us windows version and that behaves differently.
It failed with Apples default unarchiver that is built in the Finder.

try Stuffit Expander with ZFS with NFD

Thanks.

Apple's Archive Utility (not Finder) usually handles .zip files.

Can you reproduce the problem with ZFS with NFD with an alternative to Archive Utility?

It's not that I could not work around the problem, it's that I don't like ZFS behave weird and I have to start working around it's quirks.
I could not get the file again so I could not test it. But I just got something to return to amazon and saved the resulting pdf on my zfs disk. Well the name is 'Rücksendung' which I could neither open nor remove nor rename in Finder. But I could remove it in Terminal. I then touched 'Rücksendung' File in Terminal and the file was neither to rename nor to remove in Finder !
So simple to reproduce now.

Digging a little deeper

OK – thanks. I wanted to rule out the possibility of an issue with Archive Utility.

Which app was used to save the PDF? Was the save performed through a print dialogue?

If a web browser, was the save with Adobe's plug-in?

In System Preferences, what's your preferred language?

British English here.
