Just call sqlite3_exec with the proper ATTACH as you would on the command

sqlite3_exec is enough.)

Actually UTF-8 is the better choice compared to UTF-16. I would start
turning on UTF-8 as the character set on your web server and ensure that it

This gives browsers a hint about the text encoding to use to render pages.
I built something like that where each word was translated into a token
and a key built from the token and the position of the word and used to
build a tree. The tree access was fast and could probably be adapted to
