Unfortunately I'm using SQL Server and not MySQL, thank you for the
It says add some unicode support! (Some is an importante word here).
Sorry, I should have worded my question better. I was mostly interested in
finding out what the extent of the added support was :).
Thanks for the tip on the test cases. Unfortunately I still haven't had any
luck. The SELECTs still aren't returning unicode, just latin1 binaries. I'm
using Arch Linux, unixODBC and freeTDS. Using wvarchar always fails with a
bind error - looking at the c code, it looks like a unixodbc or freetds
error. At this point I'm about ready to throw the towel in.
Thanks for the help,
