According to ISO/IEC 8859-7 (see http://en.wikipedia.org/wiki/ISO/IEC_8859-7), the
byte values 0xA1 and 0xA2 should decode to U+2018 an U+2019 respectively but .NET encodes them to U+02BD and U+02BC respectively. Reversely, the character U+2018 an U+2019 both encode to 0x27.
As this violates said standard, .NET framework should not claim conformance to that standard,
eg. on http://msdn.microsoft.com/en-us/library/system.text.encoding.aspx or in the EncodingInfo.Name property for that encoding. Alternatively, implementation should be changed to match the standard
