You could be more verbose and say that lsof or sudo aren't installed

- And then I got:

I reinstalled airtime but after that I get:

Any luck?

Maybe take a look into /var/log/airtime/pypo-liquidsoap/ls_script.loq

We had another user report a similar problem here:

and it appears to be related to a file having a "smart-quote" in its file name.

Since we cannot reproduce this, could you try looking into the "convm" utility. 

This may be related to the fact that before you created a UTF-8 locale, you were writing file names in one type of encoding, and now that you have a UTF-8 locale, your newer files are in a different type of encoding.

Also confusing is why Python is decoding your filename using an ASCII codec (when it is supposed to be in UTF-8 decoder)
