General Unicode requirement in INF files

INF files should be saved and encoded as Unicode (UTF-16 LE); they must not be ANSI or UTF-8.

To check for Unicode in INF files:

  1. Use Microsoft Notepad to open the INF file.
  2. On the File menu, click Save As.
  3. If ANSI appears in the Encoding field of the dialog box, change the encoding to UTF-16 LE (Unicode on older versions of Notepad) and save the file under a new name.

This figure shows the Save As dialog box for a file that has ANSI encoding:

The proper default value is shown in this figure:

On older versions of Notepad, it may look like this figure:
