use setVariables instead of cfset?
In general, for static variable names, you should use cfset, or

Because CF can't do unicode, you can't use nvarchar, ntext or
nchar, you must use varchar, char and text.
U I don't think so. Our entire site is built on nvarchar
fields w/ SQL 7 CF4.01. No problems of any kind. Non-US form data
