It might be related to Unicode. However, I am able to use the database using sqlite3_open and sqlite3_exec <i>without</i> issues when not loading an extension.
I stepped though my code and ajay.db��0 materialises as soon as I execute
> select load_extension('fileio.dll')
using sqlite3_exec.
I tried to compile fileio.c (using CL) with no success. I acquired fileio.DLL from [this link](https://sqlite.org/forum/forumpost/0eb1b89441f4cd63?t=h) in this forum.
It is possible that fileio.dll from here has supplementary code that could account for what I am experiencing.
In fact, I am certain of it since I can run the SQLs in my code in the CLI (unlike SQLITE3.DLL, SQLITE3.EXE has ReadFile etc built in) without any anomalous behaviour.
(... Can I get hold of fileio.DLL from somewhere else?)
