My colleague couldn’t open PDF documents from Zip archive that I sent her. I spent some time reasearching… And it turns out that every major operating system ignores Zip specs and uses different encoding for file names. I had to remove Lithuanian Ą and Ū from file names to make my Zip archive Windows-compatible. That’s insane!
