Oracle CHR(164) to VARCHAR(10)

Last Modified: 2012-04-24
I'm experienced in SQL Server but new to Oracle.  I've created a Oracle XE 11G database, table and inserted several records successfully.  But I'm unable to insert extended characters as shown below.  My column's datatype is VARCHAR(2000) but I get the error 'ORA-01722: invalid number' upon attempting to CAST CHR() to VARCHAR.  What am I missing here?

insert into tblThreadContent
('Regular text followed by an extended character, with space ' + cast(chr(164) as varchar(10)))
