@sdetweil topic solved. I’ve downloaded older version from the first guy, not the forked one. Now everythings works perfect from shbatm.

@KristjanESPERANTO thanks a lot .
Sorry I mean umlauts don’t work on both node run query (hafas and hub) but on the HAFAS module it had simply required less …less precise data and forgave the absence of umlauts. Output (results) were clearlier. On HAFAS I found my station (18 März Straße) by myself on December 2025, and on new hub module I needed your help .
edit.
thanks for update - new module is now absolute.
After one hour battle with gemini help I captured the umlauts.
Set system-wide locale explicitly:

Edit /etc/default/locale:
Bash

sudo nano /etc/default/locale

Replace its content with:

LANG=en_US.UTF-8
LC_ALL=en_US.UTF-8

Force locale variables in user profile:
Bash

   echo 'export LANG=en_US.UTF-8' >> ~/.profile
   echo 'export LC_ALL=en_US.UTF-8' >> ~/.profile

Reboot the Raspberry Pi:
Bash

    sudo reboot

After the reboot, npm run query and Node CLI environments properly retain all Unicode characters .

@sdetweil
Ok sorry , in hurry.
Why? Because mnm-pages does not support keyBinding module. I want to move pages manually before I order IR touch frame.

@KristjanESPERANTO I know topic is old…well instead of searching inside the app, I have been digging in Google browser . " Magic mirror modules"
