When the three characters were added to Hong Kong SCS, we considered 
defining Adobe-CNS1-5. Defining a new Supplement for only three glyphs 
didn't seem the right thing to do, so we silently updated Adobe-CNS1-4 
with three additional glyphs. We chose this approach because we were not 
aware of any Adobe-CNS1-4 implementations.

One thing that has prevented us from defining Adobe-GB1-5 to include the 
glyphs from the minority scripts is the fact that they are complex scripts 
requiring complex rendering. We don't want to add glyphs that could not be 
meaningfully rendered. We are, however, always considering these glyphs. 
We have found that the GB 18030-2000 requirements state that minority 
characters are recommended. Applications must deal with their code points,
 however.
