Export data form in text file with encoding UTF-8

[Eric.promattex]

I have a pdf form with javascript to export some data in fichier text with the following script :

var Data = 
	this.getField("Texte3").value	
var doc =
	this.createDataObject({cName:"Data.txt",cValue: Data});
	this.exportDataObject({cName:"Data.txt",nLaunch:2});

If there are no special characters in the field, the text file is in UTF-8, but as soon as there is a special character, the text file is in ANSI.

Would there be a solution for the text file to remain in utf-8 but if there are special characters in the field?

Use the setDataObjectContents method to populate the file. That way you would be able to specify the encoding directly. There's an example of that in the JS reference for that method.

thank you for your reply
Could you give me an example with the above script?

var Data = 
	this.getField("Texte3").value	
var doc =
	this.createDataObject({cName:"Data.txt",cValue: Data});
	this.exportDataObject({cName:"Data.txt",nLaunch:2});

Did you look in the JS Reference?

the JS reference is this: https://www.t10.org/ftp/js_api_reference.pdf?
yes on page 338 but I don't understand their example

Try this code:

var myData = this.getField("Texte3").valueAsString;
var myDataStream = util.streamFromString(myData, "utf-8");
this.createDataObject({cName:"Data.txt",cValue: ""});
this.setDataObjectContents("Data.txt", myDataStream);
this.exportDataObject({cName:"Data.txt", nLaunch:2});

Thank you very much, it works.
Thanks in any case for the example. I don't know how long it would have taken me to achieve this result.
Thanks again.
