Issue converting sav file to csv

[clinton bowen]

Hello,

I am trying to convert a sav file from slavevoyages.org:
https://www.slavevoyages.org/documents/download/tastdb-exp-2020.sav

I am using pspp v1.4.1 from the ubuntu jammy package.

When I run `pspp tastdb-exp-2020.sav tastdv-exp-2020.csv` I get errors
like "tastdb-exp-2020.sav:1.251: error: Syntax error at `...': Bad
character U+0000 in input."

I suspect there are null characters in places they shouldn't be.  Is
there a way to correct this?

Thanks,
Clinton
