Since ASCII is really only a 7-bit code, I use the high bit to indicate italics. I wrote a Java program for printing; it makes all characters 16-bit, despite their starting as 8-bit,so no problem. For emacs, I wrote the necessary hooks to catch high bits in a file's 8-bit characters; on readin, the high bits are cleared, and characters intended to be italic get an italic property, instead; on writeout, characters with the italic property get their high bits set; no sweat, the hooks work. I want to be able to copy an emacs buffer, with some characters having italic mode set, and paste that into an email compose buffer, and have the italics set in the email buffer; this should work, but it doesn't, whoknows, who cares, why not. But if I copy/paste a .odt file, with italicized characters, the italics show up as intended, in the email buffer. But, how to generate the .odt file? Pandoc, of course, but pandoc only eats emacsfiles if they're Org mode. So, I wrote a lisp function, to generate the Org mode file I need, from fundamental-mode-plus-hooks emacs. And yes, pandoc will eat the Org mode file, as intended, and convert it to .odt, as intended, and I can copy/paste the .odt, and italics show up, as intended, in the email buffer. Except, Org mode is very crude: it indicates italics by surrounding text by slashes, and so, what if the original text contained slashes, intended as ordinary text, not escape characters? What if the slashes themselves are intended to be italicized? Is there some way to tell Org mode to use different escape characters? Or to make ordinary emacs characters with the italic property, copy and paste, like God intended?

First problem: what, exactly, is the zero-width space character? I won't be entering text with my fingers, a lispfunction I wrote will be inserting the characters I need. So, exactly what 8-bit value is a zero-width-escape? 00000000?The example in 17.12 seems to put the zero-escape after the control character it's supposed to affect, but then theeffect of it balances forward. 12.6 tells me I also have to put a comma before any line beginning with a star, despitethe fact that my only purpose was to deal with italics. I need to write a function which works, first time, every time;I can't keep playing around with each piece of text it applies to, until it works on that one. OK, helping me get afunction written is not your job, but I shouldn't need .odt and/or pandoc; I should not have needed your help,at all: plain vanilla copy/paste in emacs should bring along text properties within the scope of the copied text. > Still, I do appreciate your help. Org does not perform any kind of format conversion when you kill selection by default. There is however a third-party package that provides some (limited?) support for clipboard conversion: https://github.com/jkitchin/ox-clip Note that Org is a markup format with all the relevant advantages and disadvantages. The requirement to escape some special symbols is one of the disadvantages. You can insert zero-width space using C-x 8 <RET> or by its hex number or directly copying it to (insert ""). Note that Org does provide the means to convert Org markup into alternative markups like HTML. This is done using export functionality: https://orgmode.org/manual/Exporting.html#Exporting Hope it helps. Best, Ihor ^ permalink raw reply [flat|nested] 4+ messages in thread

I do not know how it is implemented on Windows, but on Linux applications declares several MIME types for selection: UTF8_STRING, text/html, etc. Applications that can insert formatted text use HTML, pure text application query plain text. To inspect available types the following command may be used: xclip -target TARGETS -out -selection CLIPBOARD AFAIK emacs can not provide several types for selection content and xclip does not have such feature as well. When you are sure that namely formatted text is required, you can try to feed markup to xclip -target text/html. I do not think that Org is appropriate tool for your purpose, escaping is tricky, zero-width spaces when used in such case should be removed from the target document. Constructing org-element AST directly may be more reliable. Within Emacs yank-handler text property may help to copy text from your specific encoding to other buffers. ^ permalink raw reply [flat|nested] 4+ messages in thread
