Example of the Unicode text file format (Database name: database1, Table name: product-info1)
Unicode text files can be created using a text editor or spreadsheet software program. The method for saving
Unicode text files in Notepad or Excel is as follows:
• In the text editor (Notepad, an accessory of Windows

7), select [Save As] from the [File] menu, and select
"Unicode" as the character code to save the file.
• In the spreadsheet software program (Excel 2010), select [Save As] from the [File] menu, and select
"Unicode" as the file type to save the file. When a Unicode text file is created using a spreadsheet software
program, tabs are automatically inserted by saving the file. Therefore, it is not necessary to insert tabs into
the file in the spreadsheet software program.
