Same here:

# sudo java -jar log4j-detector-2021.12.13.jar /usr > out.txt
Exception in thread "main" java.nio.file.InvalidPathException: Malformed input or input contains unmappable characters: /usr/share/ca-certificates/mozilla/NetLock_Arany_=Class_Gold=_F??tan??s??tv??ny.crt

It also happens with this:

/etc/ssl/certs/NetLock_Arany_=Class_Gold=_F??tan??s??tv??ny.pem

I appears the culprits are all symlinks. And while their file names contain "garbled" chars, that should no causes the program to abort :)

Here's the name in ls -la output:

'NetLock_Arany_=Class_Gold=_F'$'\305\221''tan'$'\303\272''s'$'\303\255''tv'$'\303\241''ny.crt'

When viewed as UTF-8 (on Debian 10) in bash with TAB-completion, it shows up as:

NetLock_Arany_\=Class_Gold\=_Főtanúsítvány.crt

So, it's a legal UTF-8 name, it appears to me.

After removing the file and the same-named symlink to it in /etc/ssl/certs/, the program runs through "/" fine.

Should be fixed now! (latest version - just pushed)
