Dimensions CM 14.5.3 Desktop client

I create a new Request and add a text in the detailed description with some special characters.

Then I open the request via Browser (no matter if Google Chrome or Internet Explorer)

Dimensions adds some more special characters in the detailed description.

examples:

°
–
§
$
„
“

is shown as 

°
–
§
$
„
“

But if I open again the Detailed description, I don't see the additional special characters, I just see the characters that I have added.

I tried to open the same request then in the Web Client and there I see the additional special characters, I can remove/correct them and after this the are also not visible any more in the browser, when I open the request in the desktop client. And after saving the detailed description in the web client, I now also see the additional/wrong charcters also in the desktop client when editing the detailed description.

And after editing the detailed descriptions once in the web client, I can also edit it now again in the desktop client and the added § or ° will stay as the are.

For me it looks like saving the detailed description in the desktop client and the web client works different. Unfortunately most users use the desktop client and it is a nightmare to have unwanted special characters in the technical description.

Is there any way to avoid the addition/change of this special characters in the desktop client? °C and § are not very unusual characters and the only way I see at the moment is to tell the users: please use DEGREES and CHAPTER instead of ° and §. This does not work in the daily work.

It does not matter if I use the normal notepad.exe or notepad++ for editing the detailed description.
