The parameter file contains the data for parameters that were defined in the script. This file, stored in the script's folder, has a *.dat extension. When running a script, Vusers use the data to execute actions with varying values.
By default, VuGen saves the parameter file with your machine's encoding. When working with languages other than English, however, in cases where the server expects to receive the string in UTF-8, you may need to convert the parameter file to UTF-8. You can do this directly from Notepad, provided that you are working with Windows 2000 or higher.
Select Vuser > Parameter List and view the parameter properties.
In the right pane, locate the parameter file in the File path box.
With the parameter table in view, click Edit in Notepad. Notepad opens with the parameter file in csv format.
In the Save as type box, select All Files.
Click Save. Notepad asks you to confirm the overwriting of the existing parameter file. Click Yes.
In the Encoding box, select UTF-8 type encoding.
VuGen now recognizes the parameter file as UTF-8 text, although it still displays it in regular characters.
