Here are three files, two of them get wrong file name.

> 一.txt --\> txt  
> 二 --\> 二.txt  
> Three.txt --\> Three.txt

Here is the script on button.  
I think the function get the right parameters.

```auto
def runAction(self, event):
	# Grab the selected row
	selectedRow = self.getSibling("Table").props.selection.selectedRow
	pyDS=system.dataset.toPyDataSet(self.getSibling("Table").props.data)
	id=pyDS[selectedRow][0]

	# Use the id to grab the file data out of the database, along with its corresponding name.
	query = "SELECT filename, filedata FROM Files WHERE id = ?"
	args = [id]
	data = system.db.runPrepQuery(query, args, database='file')
	 
	# Pull out the file name and data
	filename = data[0][0]
	filedata = data[0][1]
	self.getSibling("Label").props.text=filename
	# Download the file
	system.perspective.download(filename, filedata)

```

does your machine support such characters as filenames? (can you create them with the right name by hand?)

Yes, they work well in my email. The names are basic chinese word, and I’m sure their code is utf-8.  
thanks.

welh there seems to be a problem with encoding so maybe try to use a different encoding i guess  
`filename = filename.encode('utf-8')`

I don’t think that is an encoding problem. The second file showed right word, but with Extensions that shouldn’t exist.  
And I encoded the filename to utf-8 before upload them.

Anyway, I’ll try your advice tomorrow.

</div>

A directly scripted attempt (`system.perspective.download("二", "data")`) worked fine for me:

 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/c/fc98bc38f985c000dffe0701d17a350e8f8e331c.png)

If you `system.perspective.print` the filenames before calling `system.perspective.download`, are they showing up correctly?  
What Ignition version is this?

I guess yes, but here is an encoding error in console.

Please allow me to recapitulate the phenomenon on my PC.  
First file get no file name but just extension.  
Second file get correct file name but with extension that shouldn’t exist.

The first phenomenon is a real problem. when I tried to find out, I noticed the second one. Files without extensions are not commonly used, so I think that is acceptable.

Ignition version is 8.1.7 , windows 10.

Thank you 🙂

I found the bug. We’re passing the `Content-Disposition` header from the backend, which is what suggests the filename to the browser. However, [RFC-2047](https://datatracker.ietf.org/doc/html/rfc2047) dictates that this header name and value be US-ASCII, which we are _not_ correctly encoding to.  
I’ll file the ticket.
