are you testing this in the sqlite3 shell or in your own program? You should have no issue getting thisdata,
sqlite3_column_text followed by sqlite3_column_bytes (the byte count is set when the data is fetched in some format). without modification, you can either excape \0 with '||char(0)||' ... "My data \0with binary". "My data "||char(0)||" with binary". or use a parameter binding to get the value stored in the database. The row with a nul should be stored in the database; but the command line shell will not return the right values for selects; it will truncate that returned values at the \0.
