Ok, I understood your point.
 
But as per RFC 2865,
what is the meaning of then "UTF-8 encoded 10646 [7] characters", the [7]?
7 stands for what over here?

And one more thing as per RFC 2865,
1) As per this new RFC only only we need to support US-ASCII not any other character set, right?
2) Does free RADIUS only supporting US-ASCII ?

 No.  7 bit US-ASCII is a subset of UTF-8.

 The statement is required for international text.  i.e. non US-ASCII.

 Read the UTF-8 RFC.  This is all documented elsewhere, and is not part
of FreeRADIUS.
