Continuation (B) - signifies whether the character data represents a new character (0) or is a continuation of 
the character described by the previous character descriptor block and its data (non-zero).  If the continuation 
byte is non-zero the bytes following it are interpreted as character data. 

 

Descriptor size (UB) - specifies the character descriptor size in bytes. 

 

Class (UB) . indicates the character format.
