Well, I haven't checked Oracle, but when you install the unicode AR System on MS SQL today the columns created are of type nchar. For example the C1 field is nvar(15). So it looks like the db side is created already OK. I can even insert the offending characters using SQL and get them displayed in ars without any problems.

Probably implemented different function names because some other products do: http://www.oracle.com/technology/oramag/oracle/03-mar/o23sql.html In Oracle, you can define the limits of a column like this (if using a unicode character set): VARCHAR2(3 CHAR) This sizes the column such that the limit is on the number of characters, not bytes. Seems this would be a hefty change for a .x release, but could be implemented in a major release since people will be using the installer to perform the upgrade. The reason I say hefty is because all varchar columns in the db would need to be altered to use the character limit and not the byte limit. Not sure how this translates to other db's either.
