// This implementation does not support 16 bit character sets. Since 8 bit
// character sets are supported by the class DcmByteString the class
// DcmCharString is derived from DcmByteString without any extensions.
//
// If the extension for 16 bit character sets will be implemented this class
// must be derived directly from DcmElement. This class is designed to support
// the value representations (LO, LT, PN, SH, ST, UT). They are a problem because
// their value width (1, 2, .. Bytes) is specified by the element
// SpecificCharacterSet (0008, 0005) and an implementation must support
// different value widths that cannot be derived from the value representation.
