Hello maintainers of the Debian installer,

As a follow-up on #101435, I've updated the script to detect more cases where
glyphs are missing, but used in translations.

The steps required to run the script are mentioned in the header of the script.

If needed, I can provide the file 'collect' (the currently used translations of
all udebs in Bookworm)

Attached is also the output of the script, which lists the missing glyps

With kind regards,
Roland Clobus
