_appendN($inboundData)   X-Ref
This function will intercept all the literals used in the SQL, prepending the "N" char to them
in order to allow mssql to store properly data sent in the correct UCS-2 encoding (by freeTDS
and ODBTP) keeping SQL compatibility at ADOdb level (instead of hacking every project to add
the "N" notation when working against MSSQL.

The orginal note indicated that this hack should only be used if ALL the char-based columns
in your DB are of type nchar, nvarchar and ntext, but testing seems to indicate that SQL server
doesn't seem to care if the statement is used against char etc fields.

param: mixed $inboundData Either a string containing an SQL statement
return: mixed
