Description

TEncoding is a mostly abstract class that contains various methods to deal with different encodings in single- and double-byte strings. In practice, one instance of a descendent of this class for each needed encoding can be instantiated and used. The class contains several class methods and properties to create such instances, and has several often-used instances available as class properties, in particular the default encoding.
