I had this same problem. Even though I saved the CSV from Excel (2010) and selected Unicode(UTF-8) in Tools – Web options, it consistently ignored the first column.
I happened to re-open the CSV file in Notepad++ which indicated the encoding was actually “UTF-8-BOM”. Notepad++ has the ability to convert the encoding so it changed it to UTF-8 alone. Now it imports into PDB as I would expect. Seems Excel does not quite “do what it says on the tin”.
