/**\r
\r
  This function allows a program to extract a part of a string of not more than a given width.\r
  With repeated calls, this allows a calling program to extract "lines" of text that fit inside\r
  columns.  The effort of measuring the fit of strings inside columns is localized to this call.\r
\r
  This is a deprecated API. No Framework HII module is calling it. This function will ASSERT and\r
  return EFI_UNSUPPORTED.\r
\r
  @param This            A pointer to the EFI_HII_PROTOCOL instance.\r
  @param Handle          The HII handle on which the string resides.\r
  @param Token           The string token assigned to the string.\r
  @param Raw             If TRUE, the string is returned unedited in the internal storage format described\r
                         above. If false, the string returned is edited by replacing <cr> with <space>\r
                         and by removing special characters such as the <wide> prefix.\r
  @param LanguageString  Pointer to a NULL-terminated string containing a single ISO 639-2 language\r
                         identifier, indicating the language to print. If the LanguageString is empty (starts\r
                         with a NULL), the default system language will be used to determine the language.\r
  @param BufferLength    Length of the StringBuffer. If the status reports that the buffer width is too\r
                         small, this parameter is filled with the length of the buffer needed.\r
  @param StringBuffer    The buffer designed to receive the characters in the string. Type EFI_STRING is\r
                         defined in String.\r
