Re: GB 18030 question

The thing bother me is the GB18030 defined the mapping from that GB18030
code point to a private use area but it also print a glyph in that
mapping. Since those unicode code point are in private user area, it is
not good to print a glyph there in the standard. Do we NEED to display
those code point AS what it print on the GB18030?

By printing a glyph for those character in the GB18030, it really
DEFINED what those characters should be in Unicode- which I think is not
the right thing to do for GB standard body. Is that a error or not? (by
printing the glyph in the standard)
