Thank you for clarifying this in this discussion. AF> ... The symbol: AF> - is typically used as part of computer applications (e.g. CAD symbols) AF> - has well defined user community / usage AF> - always occurs together with text or numbers (unit, currency, estimated) AF> - must be searchable or indexable AF> - is customarily used in tabular lists as shorthand for characteristics (e.g. check mark, maru etc.) AF> - is part of a notational system AF> - has well-defined semantics AF> - has semantics that lend themselves to computer processing AF> - completes a class of symbols already in the standard AF> - is letterlike (i.e. should vary with the surrounding font style) Do you agree that a considerable part of the Wingdings/Webdings symbol set does not comply with even a single one of these criteria? This, in short, was the concern expressed in N4085. Then, we expressed that even *if* a larger set of "indicators" is applied (which were presented exemplarily in the short list cited in this discussion), a considerable part of these symbols fails. This, and only this, and only in this context, was the purpose of the "indicator" list. AF> ... If one agrees with the premise of encoding the Web/Wingding sets AF> "compatibility sets" ... (Which we in fact did not agree to when compiling the comments in WG2 N4085, but after we learned that at least those competitors of Microsoft who are engaged in the UTC do not oppose to this view, we also oppose no longer.) - Karl
