How to force markup without spaces

How to force markup without spaces

[cinsky]

Hi,

AFAIK, if the markup syntax (=code=, *bold*, ..) is directly followed
by non-whitespace characters, then it will not be marked-up:

   =hello=there
   /not/italic

This may be right decision on English text, but in some languages, the
postposition (grammar) will be postfixed without spaces into the
previous noun, so it will be the trouble.  (Following text contains
Korean characters in UTF-8, you may need additional korean font to
read properly)

   =printf=는
   =bold=로
   =철수=는

I'm sure that some other languages will have same problem
(e.g. Japanese or Chinese).

Is there any way to force mark-up on this situation?

If this pattern cannot be implemented easily, how about to introduce
new escaping character to prevent to insert whitespace between
marked-up text and the following postfix text?  For example:

  =printf=\is      => rendered in HTML: <code>printf</code>is
  *bold*\asdf      => rendered in HTML: <b>bold</b>asdf
  /철수/\는        => rendered in HTML: <i>철수</i>는

I can't say the above solution is well-designed, but I'm sure that
you'll get the point.

Thanks.

Yes, thank for the solution.

By the way, I'll prefer "word joiner" character (U+2060) to "zero width
space" character (U+200B),
because postpositions (grammar) should not be separated on line-break
policy.

Anyway, is there any plan to implement this feature in other way?
Using the solution that you provides makes the org document stick to the
unicode,
so it can't be used in other character encodings.

Thanks.

More precisely this can be included when we decide to drop support 
of Emacs 22.

Does anyone know what is the current backward compatibility state
of major native Emacs packages (Gnus/ERC/etc) wrt Emacs 22?

Since emacs has released 28.1, Could this problem be solved?

Although we have the zero-width space workaround, for some fonts the
character will not be zero-space. So it would be nice to solve this
problem.

That thread references yet another thread at
http://thread.gmane.org/gmane.emacs.orgmode/59881/focus=59971
However, gname links are no longer working.
Do you happen to know which thread id or subject the link is referring
to in the mailing list archive?

To add regarding the markup without spaces, we have discussed something
called "inline special blocks" in
https://orgmode.org/list/87a6b8pbhg.fsf@posteo.net
Such blocks can be used as an alternative markup.

Another idea we have discussed is using something similar to Markdown
format: **bold**, //italics//, __underline__, etc. It is less verbose
compared to the special blocks, which should be valuable for
Japanese/Chinese/other languages with no spaces between words.

Best,
Ihor

*N*ations. 2012-09-05  8:05 UTC

However the suggestion was namely to use U+200B ZERO WIDTH SPACE and it 
is actually implemented since `org-emphasis-regexp-components' currently 
contains [:space:].

The U+2060 word joiner character (from this thread) is not a space, so 
currently it can not be used in such role. Recent mention of this character:

K, could you, please, clarify what is your particular use case? Some 
other workarounds, e.g. custom links, was discussed during last couple

My bad, I misunderstood the "feature" mentioned in the old post.

My use case is to emphasize chinese characters without spaces being inserted, even those zero-width spaces. For example "中文*测*试" should be enough to emphasize "测".

I am using zero-width spaces right now, and it works fine in org-mode buffers, but if exported to latex-pdf files, the U+200B ZERO WIDTH SPACE character will not be zero-width for certain fonts. So I hope not to use that character.

By the way, it seems that my use case has already been implemented by markdown-mode. In a markdown-mode buffer "中文**测**试" will certainly make "测" bold.

I have not tested it, but I expect you can use
- export filter that removes zero-width spaces at the last export stage. 
I assume that your documents do not contain them besides markup workaround
- #+latex_header: \DeclareUnicodeCharacter{200B}{}
- custom link

    #+begin_src elisp :results none :exports both
      (org-link-set-parameters
       "sep"
       :export (lambda (path desc backend)
	       (if (org-export-derived-backend-p backend 'org)
		   (org-link-make-string (concat "sep:" path) desc)
		 (or desc ""))))
    #+end_src
    "中文[[sep:][*测*]]试"

In other thread we are discussing advantages and problems of switching 
from PdfLaTeX to LuaLaTeX for non-latin scripts. The latter is a Unicode 
engine. I am curious what is your opinion from standpoint of Chinese 
language, namely amount of required customization in both cases. I 
think, it is better to either start a dedicated thread, or find the part 
of discussion related to fonts and babel (LaTeX package) setup.

I tested the second workaround, and replaced the \DeclareUnicodeCharacter{200B}{} sequence with \newunicodechar{​}{} sequence since I am using xelatex, which does not support the former.
It works fine so far.

As far as I know, Chinese users commonly use ctex package https://ctan.org/pkg/ctex to handle Chinese typesetting problem, and they prefer xelatex and lualatex over pdflatex. They don't support more fonts when using pdflatex, compared with using xelatex etc. (you can see that on page 7 of their pdf document). So I just use xelatex and don't have much experience using pdflatex.

When using ctex, you just need to declare \documentclass{ctexart} (ctexart is a ctex version article) to use Chinese characters. Then if your system has the required default fonts, the pdf documents should be OK.
