So I've been looking for this to work for some time now. I'm sure there must be a solution as I can't believe that no one in China or Japan have ever tried exporting contacts. What I've found so far is this Microsoft forum discussion that doesn't come to any conclusion, as well as this SuperUser question that doesn't give a satisfactory answer as it only says it works within Outlook.
So, my issue here is that I have a lot of Outlook contacts that I would like to import into SalesForce. SalesForce can take any CSV file and import it as contacts. When I export my Outlook contacts all the Japanese characters become question marks. If I import this into SalesForce the question marks remain, indicating that it's not that my editor can't show the characters, it's that the characters are really messed up (question marks in Excel, Wordpad, Notepad, Notepad++).
Troubleshooting so far
If I manually change some of the question marks to the proper Japanese characters and import this into Outlook it works - indicating that SalesForce can use Unicode characters. The exported CSV file is saved as ANSI encoding, so the issue is how Outlook encodes the export.
How can I force Outlook to export the contacts as CSV with Unicode encoding? Is this an Outlook issue or is it a system setting where CSV files default back to ANSI? How could I go about changing this?
