Thanks
@luyenok for creating this usb script for removing some CHN/JPN languages to free space at the CMU (see post#7 above).
I would not recommend to use this script, if you are in the ADR/4A N region/have this firmware region, as it might happen, that you then see some symbols/icons missing.
When I deleted all these languages (EU firmware), I only missed one icon in the AIO Speedometer Tweak: the average icon (round circle with a bar through it):

Then I tested/deleted (via SSH) all the fonts one by one - after each deletion, I had to reboot. Finally I found it. The font, which is necessary for this icon being displayed correctly is the font "
HeiseiKakuGothW5_213_C.ttf" in the /jci/fonts/CHN folder. The same font might be in other folders, but this one in this folder is solving the speedometer average icon issue. So this should not be deleted.

Therefore I slightly adapted the tweak of luyenok (and added my sd* improvement mentioned some posts before) - see the attached file. Just rename it (delete the ".pdf" in the name and then unzip it).
Edit: I also attached this font here. Just rename it like above. Just in case someone already deleted it and needs it/wants to install it again.
