* @class UTF8_Latin1_Translator
*
* @brief Codeset translation specialization - Manages Byte Order Marker
*
* This class performs the codeset translation:
* - Native: ISO-8859-1 (i.e. Latin 1)
* - Stream: UTF-8 (8 bit unicode mapping)
*
* When writing chars, it is possible to raise a DATA_CONVERSION exception
* because some valid Latin codepoints map to 2-byte utf-8 codepoints.
*
* When reading strings, it is possible to raise a DATA_CONVERSION exception
* because the string may include utf-8 unicode codepoints > 0x00FF.
