Then why do you persist in public discussion of suggested codepoints for such purposes? If it is for local, proprietary use internal to some implementation, then the only one who needs to know, think or care about these codepoints is the person creating that implementation. > Publishing a list of Private Use Area code points would have absolutely no purpose at all. > mean that such > display could be produced using a choice of fonts from various font makers > using the same software Now you are talking interchange. Interchange means more than just person A sends a document to person B. It means that person A's document works with person B's software using person C's font. (An alternate term that is often used, interoperate, makes this clearer.) > I feel that an important thing to remember is the dividing line between what > is in Unicode and what is in particular advanced format font technology > solutions And best practice for advanced format font technologies eschews PUA codepoints for glyph processing. You've been told that several times by people who have expertise in advanced font technologies, an area in which you are not deeply knowledgable or experienced, by your own admission. > yet they are not suitable for platforms such as Windows 95 and > Windows 98, whereas a eutocode typography file approach would be suitable > for those platforms and for various other platforms. Wm, if someone wanted, they could create an advanced font technology to work on DOS, but why bother? Who's going to create all the new software that works with that technology, and make it to work within the limitations of a DOS system? Your idea is at best a mental exercise, and even if you or someone else built an implementation, what is not needed is some public agreement on PUA codepoints for use in glyph processing. > I am hoping that the eutocode typography file approach with display glyphs > added into the Private Use Area will be a useful technique in many areas, > including, yet not limited to, interactive broadcasting. If your ideas were to get used in some area like interactive broadcasting, the use of PUA codepoints for rendering purposes would be relevant to that technology, and out of scope for discussion on this list. - Peter --------------------------------------------------------------------------- Peter Constable Non-Roman Script Initiative, SIL International 7500 W.
