Quick announce:
We've recently released Unicode version of Store Manager
you can find all details here
http://www.magneticone.com/store/X.Cart.Modules...Mods/Store.Manager.for.X.Cart#versions_history
If you had any issues with special characters - like European Umlauts, Chinese symbols, this was the change you needed.
There are also few more important speed and quality improvements.
I welcome everybody to upgrade or give it a try if you still don't use it.
