[sqlite] Windows Unicode Support

[Jeff Thompson]

Hi, I've recently gone through the work to convert my windows 
application to unicode. A ran across a couple of the sqlite3 API calls 
that don't seem to have unicode versions, namely:

sqlite3_exec
sqlite3_mprintf
I switched all of my sqlite3_mprintf/sqlite3_exec calls to 
sqlite3_prepare16/sqlite3_step calls and use sqlite3_bind_text16 to bind 
parameters instead of using the '%q' quoted string support provided by 
sqlite3_mprintf.

While this works fine, I was wondering why there are no unicode versions 
of these (and possibly others) functions?

Thanks,
