Detailed Description

Class used for decoding Teletex strings. The TeletexString type is not fully supported by this library. Instead the decode methods perform a direct conversion from 8 to 16bits by adding null characters in the second byte of each character. This will work as expected for cases where the string contains ASCII data. As this is non-destructive, the original data can be retrieved by performing a Copy to an 8-bit descriptor.
