Problems with german characters ä, ü,ö in NodeRed editor V 4.0.2

[KRR]

Since the installation of 4.0.2 amd and nodejs 22 i have trouble with displaying german characters ä,ü,ö in the editor and in the debug window. When i restart the docker container, everything is okay. After Nodered is running again, the problems occur again after approx. 1 day.

Editor:
When i switch to german language in settings the characters in the node names are shown as ?.
See. image EditorlanguageGerman.

debug window:
If a flow is triggered with a payload, containing ä,ö,ü the output of a debug node is not shown in the debug window. the flows itself are working correctly
see images debugwindows
I used Developer tools in the microsoft edge browser and i got an error message in the Console.
see image ErrorWebsocketConnection

There are any settings for UTF-8, Codepage, ... available in NodeRed?

Hi. The fact you state it is ok for 1 day then not ok, suggests a transient issue. Additionally it appears to be websocket related - getting NON utf-8 characters transmitted. Perhaps something in your flow or on your computer. Have you tried a different browser? Have you tried running Node-RED outside of docker? Are you using the official node-red docker image?

I tried reproducing your issue by adding a delay node with the name ä,ö,ü and injecting the same string, then changing from English to German - and everything appears to work correctly.

NOTE:

• Not running in docker
• I am running NR 4.0.3 and on NodeJS 18.x

node-red - node name with accented characters not displayed correctly - lead to deployment issue

Hi Steve, thanks for your reply.
I will get in contact with the administrators to check your proposals

[KRR]

Ok. I will do it
