How did you transfer the UTF8 data with PB functions?

Using setdatabaseblob().
I store text files and images.
Then users can view them in DB Browser browser For SQLite.
This is convenient when the DB schema does not have every fiddle faddle field defined. I can dump a ton of nosql data in a few blobs. Later if they want to query, I can write custom SQL to extract info.
