Displaying music beams using the unicode standard
The Unicode Standard version 6.3 specifies character codes for music in the range 1D00-1DFF. Two of these are 1D173 (Begin Beam) and 1D174 (End Beam).
Is the purpose of these character codes for specifying the ligature start and end points of a beam in the resulting output? If so, what's required to achieve the desired output?
