This thread has gone on for a bit and I question if there is any more light that can be shed.
BTW, I admit to liking Asmus definition for functions that span text being a definition or criteria for rich text. I also liked James examples of the twitter use case. The arguments against italics seem to be: · Unicode is plain text. Italics is rich text. · We haven't had it until now, so we don't need it. · There are many rich text solutions, such as html. · There are ways to indicate or simulate italics in plain text including using underscore or other characters, using characters that look italic (eg math), etc. · Adding Italicization might break existing software · The examples of existing Unicode characters that seem to represent rich text (emoji, interlinear annotation, et al) have justifications. The case for it are: · Plain text still has tremendous utility and rich text is not always an option. · Simulations for italics are non-standard and therefore hurt interoperability. This includes math characters not being supported universally, underscore and other indicators are not a standard, nor are alternative fonts. · There are legitimate needs for a standardized approach for interchange, accessibility (e.g. screen readers), search, twitter, et al. · Evidence of the demand is perhaps demonstrated by the number of simulations, and the requests for how to implement it to vendors of plain text apps (such as twitter). · Supporting italics can be implemented without breaking existing documents and should be easily supported in modern Unicode apps. · The impact on the standard for adding a character for italics (and another for bold and perhaps a couple others) is miniscule as it fits into the VS model. · The argument that italics is rich text is an ideological one. However, as with other examples, there are cases where practicality should win out. · This isn’t a slippery slope. Personally, I think the cost seems very low, both to the standard and to implementers. I don’t see a lot of risk that it will break apps. (At least not those that wouldn’t be broken by VS or other features in the standard.) It will help many apps. I think the benefits to interoperability, accessibility, search, standardization of text are significant. Perhaps the question should be put to twitter, messaging apps, text-to-voice vendors, and others whether it will be useful or not. If the discussion continues I would like to see more of a cost/benefit analysis. Where is the harm? What will the benefit to user communities be? tex
