https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213013 --- Comment #3 from Kurtis Rader <krader@skepticism.us> --- Yes, you're missing something. The reason those code points are in the Arab= ic Presentation Forms code block is a historical accident. That is, contingent= on the development of Unicode over many years. From the PDF standards document= I linked to: > In addition, there is a contiguous range of another 32 noncharacter code = points in the BMP: U+FDD0..U+FDEF. For historical reasons, the range U+FDD0= ..U+FDEF is contained within the Arabic Presentation Forms-A block, but tho= se noncharacters are not =E2=80=9CArabic noncharacters=E2=80=9D or =E2=80= =9Cright-to-left noncharacters,=E2=80=9D and are not distinguished in any o= ther way from the other noncharacters, except in their code point values. They were reserved as private-use code points because they had not already = been assigned as characters (glyphs) and it was decided that another adding anot= her 32 private use code points would be useful. --=20 You are receiving this mail because: You are the assignee for the bug.=
