The combination of the ASCII and Digital Supplemental Graphic character sets is called the Multinational character set (MCS); the combination of the ASCII and ISO Latin-1 supplemental sets is called the ISO Latin Alphabet Number 1 set. These two supplemental sets are very similar, consisting of symbols and characters for English and many other western European languages.
The UPS set assigned by this property is loaded as the default when a soft reset is performed (for example, with the ResetTerminal method) or when the DECSTR sequence is invoked. The UPS set can also be specified with the Select Character Set (SCS) sequence.
