Are you 100% sure these files worked before and now does not? Can you provide screenshot of the steps you take? It's not clear exactly what you do and how it looks when you get the error.

Hi, 

thanks for your reply.

yes I am pretty suer. you can even see the diacritic files in IFS and cannot be opened now.

Here you can see the file already inserted:

Here is the error after trying to attach new pdf to PO:

Hi,

For your information, this screenshot does not show there are files with these characters in the file name, it only shows there is a document with these characters in the title (sometimes the file name also had these characters, but not always):

Go to the Document Revision screen, and the File Refs tab there and check the real file name:

Just to make sure this works at all, I just attached a file named NabídkaMŠ.pdf and it worked here:

I can also view the document.

So, not sure why it does not work for you and how this could have changed after the power outage.

Is this Apps 9 or Apps 10?

You could try to file a support case so that someone could have a closer look at the code, trying to guess why it fails for you, but not for us.

Hi, 

thanks a lot for the analysis. We have Apps10.
