I work with data from a variety of European countries, and am having trouble getting the non-standard characters (e.g. Turkish alphabet) to display correctly in my geodatabase tables. Sure, i expected this, but when I was running ArcGIS 10.1, they all displayed just fine! I tried the registry edit workaround suggested on the ESRI website, to no avail. Anybody have any better suggestions for reverting all of my '?' characters to their correct letters?
And no, i have no idea which character set they came from originally, nor which coding system they should be using.. no idea at all.
