We aren't stuck with encoding fonts into Unicode. No, the casing idea isn't actually a dumb one. As Asmus has shown, one of the best ways to understand what Unicode does with respect to text variants is that style works on spans of characters (words,...), and is rich text, but thinks that work on single characters are handled in plain text. Upper-case is definitely for most part a single-character phenomenon (the recent Georgian MTAVRULI additions being the exception). UPPER CASE can be used on whole spans of text, but that's not the main use case. And if UPPER CASE is used for emphasis, one way to do it (and the best way if this is actually a styling issue) is to use rich text and mark it up according to semantics, and then use some styling directive (e.g. CSS text-transform: uppercase) to get the desired look. Another criterion is orthography. Schoolchildren learn when to capitalize a word and when not. Teachers check and correct it all the time. Grammar books and books for second language learners discuss capitalization, because it's part of orthography, the rules differ by language, and not getting it right will make the writer look bad. But even most adults won't know the rules for what to italicize that have been brought up in this thread. Even if they have read books that use italic and bold in ways that have been brought up in this thread, most readers won't be able to tell you what the rules are. That's left to copy editors and similar specialist jobs. There was a time when computers (and printers in particular) were single-case. There was some discussion about having to abolish case distinctions to adapt to computers, but fortunately, that wasn't necessary. Regards, Martin.
