When I create and save a spread sheet as a text csv file the data is saved. When I reopen the file, all the data is gibberish

I am running Xubuntu 14.04 and using LibreOffice Version: 4.3.4.1 Build ID: 430m0(Build:1).
Default options used on saving and opening.

You have most like not selected the right character set for your computer.

I would try to use a unicode character set UTF-8, UTF-7 or UTF-16.

You also can look under the character set of your language or language group and find out which character set gives you the correct results.

Thanks, UTF-7 and UTF-8 work, but UTF-16 was the character which caused the problem.
