Creating a dxf with umlauts in text

[c_hoppen]

Hello,

I have a dxf that comes from Inventor and I need to add a text.

When I open the dxf in Mechanical 2024, umlauts are displayed incorrectly:

My first thought was that it had something to do with the Encoding. 

So I created a new dxf in AutoCAD with just one text and opened it in notepad++.

It looks like this (created by AutoCAD)

I read and write my dxf with "UTF-8 without BOM"

Encoding utf8WithoutBom = new UTF8Encoding(encoderShouldEmitUTF8Identifier: false);
List<string> inhalt = System.IO.File.ReadLines(dxfdatei, utf8WithoutBom).ToList();

System.IO.File.WriteAllLines(dxfdatei, inhalt, utf8WithoutBom);

This is what my dxf looks like:

Nevertheless, the umlauts are displayed incorrectly, see picture at the top.

I have no idea which magic word I'm missing.

Thanks for help,

Christoph

Hi,

in most cases no need to change the DXF ascii settings, instead choose the correct font/text style.

If you would upload the DXF we might try it.

Alfred,

Thanks for help. 

It turned out to be a version problem. The export format in Inventor (2025! ) was set to dxf 2004. Using dxf 2018 instead solved the problem.

I didn't have this problem with earlier versions of Inventor, so it's probably a problem with Inventor rather than Autocad.

Hi,

thank you for your feedback, good to know it's solved.

Well, I don't know Inventor, however I assume the DXF-Version setting was not set by Inventor, but instead from a user that does it.

It would be strange if any Autodesk software would export to such an old format by default 😉
