The source character set may contain locale-specific characters outside 
the basic source character set.

Actually, there are two basic character sets - the basic source 
character set and the basic execution character set (which includes the 
basic source character set plus a few control characters).  The source 
character set and/or execution character set may contain 
locale-specific, extended characters outside the basic character set.
