Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     https://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.

Using the following text I get failing pdf export: The link is not
recognized correctly but ends after the comma and the markup persists in
the PDF.

/Diesen Text habe ich leicht abgewandelt schon am Montag per E-Mail

Hi Arne,

> the PDF.

Thanks for reporting this. I’ve managed to reproduce the behaviour. I also note
that this doesn’t happen without the italic markers, i.e.

┌────
│ Diesen Text habe ich leicht abgewandelt schon am Montag per E-Mail
│ ans [[https://km-bw.de/,Lde/startseite/service/kontakt][Kultusministerium BW]] geschickt. Da hatten wir noch 2 Wochen.
└────

Is fine, while your original example,

┌────
│ /Diesen Text habe ich leicht abgewandelt schon am Montag per E-Mail ans
│ [[https://km-bw.de/,Lde/startseite/service/kontakt][Kultusministerium BW]] geschickt. Da hatten wir noch 2 Wochen./
└────

Causes issues. I also note that in the Org-mode buffer the comma seems to cause
issues. I’ve attached a screenshot, in which you can see in the “comma, italics”
situation:
⁃ The second line is not italic
⁃ The second `/' of the pair is shown (and I have Org’s entity hiding setting enabled)

All the best,
Timothy

Ooops, I forgot to mark this as a bug on updates.orgmode.org in my last email.
Let’s fix that.

The problem is with org-emph-re.

Our second component of org-emphasis-regexp-components is

> Chars allowed as postmatch.  End of line will be allowed too.
"-[:space:].,:!?;'\")}\\["

So, org-element-italic-parser will treat /, sequence as end of the
italic text disregarding that /, is part of the link.

If you try the following text, it will not export correctly as well:

/Beginning is italic 1^{/,} and tail should be italic/

Though fontification somehow works.

Or we can put some other allowed object like inline src block:

/Beginning is italic src_elisp{(message "Foo/,")} and tail should be italic/

This time both export and fontification do not work.

I suspect that we need to upgrade org-element-italic-parser in
non-trivial way to fix this.

Best,
Ihor

It was discussed earlier.

In your particular case it is possible to use "%2C" instead of comma:

     /Link 
[[https://km-bw.de/%2CLde/startseite/service/kontakt][kontakt]] link/

As a more general approach, additional emphasis marks can be added 
around link borders

     /Test/ [[https://orgmode.org/?q=query][/query/]] /test/

While I believe that during parsing of link target lookup for end of 
emphasis should be suppressed, I am not sure that it is feasible with 
current implementation. That is why I consider such behavior as a price 
for lightweight markup and its current parser.

Perhaps a “fix” could be auto-escaping problematic characters in urls when
entering links via `org-insert-link'.

All the best,

Just to be clear: while comma may be percent-escaped (`org-lint' perhaps 
would not be happy), "/?" are interpreted by HTTP server, so such 
characters must be preserved.

`org-insert-link' still may detect emphasis markers around the point and 
add extra marks. Unfortunately heuristics to detect start marker only 
(while typing text when no end marker yet) will be prone to false positives.

Maybe additional undo step while adding link is enough to alleviate the 
issue with false positives (similar to autoreplace patterns in text 
processors). If a user notices that additional markers are added 
incorrectly, she can remove them through undo. Next undo removes the 
inserted link completely.
