https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213013 --- Comment #3 from Kurtis Rader <krader@skepticism.us> --- Yes, you're missing something. The reason those code points are in the Arabic 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 those noncharacters are not “Arabic noncharacters” or “right-to-left noncharacters,” and are not distinguished in any other 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 another 32 private use code points would be useful. -- You are receiving this mail because: You are the assignee for the bug.help
