That's great news!  I mistakenly thought that the copy I got
was the latest one.  I'll go try it out right away.  :-)

Yes, something like that.  As a proof-of-concept, I tried to extend
Adobe-GB1-4, GBK2K-H and UniGB-UCS2-H to try printing these minority
scripts with Ghostscript and Founder's GB18030 TrueType font CIDCount
increased from 29064 to 31150, an addition of 2086 glyphs.

And yes, it works!  And I think I did examine the printouts visually to
ensure the glyphs match the text.  A patch is attached. Perhaps you
could use this as a reference to implement Adobe-GB1-5?  :-)
(You are free to use my patch and clean it up whatever way you like. :-)

Here is a GV screenshot:

Many thanks!
