For future reference: CSV is a terrible format for spreadsheet data.
Any by spreadsheet data I mean CSV is a terrible format for text data that will be opened in Microsoft Excel (unless you only speak English).
My objection to CSV as a spreadsheet format is it has no way to indicate the text encoding, and Excel (at least Excel 2008 for Mac and Excel 2007 for Windows) has no way of choosing the encoding when opening a CSV file. When your data is text from any number of non-English languages you will likely be dealing with characters outside the standard ‘latin-1’ character set.
Even if Excel did have a little pop-up menu for choosing the encoding when opening a CSV file, it would mean instructing your Excel-happy friends to “open as UTF-8” whenever they wanted to open your CSV data.
Wot you mean you don’t have Excel-happy friends?
