Name and File Extension change when downloading report on Edge

[Dincer]

Only on MS Edge, the file name and the extension is changing. When I try to download report as .docx, extension is changing to .txt and name is base64 like, =_utf-8_B_dGVzdC5kb2N4_=.txt

when I decode base64 to string is test.docx.

Is there any idea, how to fix this?

Thanks in advance!

Hello Dincer,

I just tried exporting a report as DOCX file from demos.telerik.com/reporting using Microsoft Edge 40.15063.674.0. The file name and extension were correct (screenshot). Please let us know if this works on your end.

Hello again,

The problem still exists. But we have noticed that when we use english characters in Name property of template (trdp file), the exported file name is correct. However, we have to use turkish characters for naming of the files. Is there any fix for internationalization?

 

Kind regards,

Dincer

Hello Dincer,

Thank you for providing more detailed information about the problem that you've experiencing.
Indeed, I was able to reproduce it either by setting foreign characters in name of the report. Searching further why this happens, it seems that this does not relates to Telerik Reporting itself, but to the Edge browser that doesn't properly encode foreign characters in name of downloaded file. This issue is reported and fixed in Edge 15063 version. 
For more information, please refer to the following articles on the topic:
- Content-Disposition header filename encoding
- Microsoft egde doesn't properly encode foreign characters in name of downloaded file
- Win10 Creators Update screwed Word encoding(?) or compatibility with Edge
