[BUG] Org export fails on $k$-ary

[BUG] Org export fails on $k$-ary

Dear all,

I would expect this to be exported to HTML and LaTeX correctly:
"A $k$-ary function has $k$ arguments"

In 12.5.1 LaTeX fragments, this use of a hyphen is documented:
"To avoid conflicts with currency specifications, single ‘$’
characters are only recognized as math delimiters if the enclosed text
contains at most two line breaks, is directly attached to the ‘$’
characters with no whitespace in between, and if the closing ‘$’ is
followed by whitespace, punctuation or a dash."

However, the HTML export result contains
"A $k$-ary function has \(k\) arguments",
which is not rendered correctly.  The first two dollar signs should
be replaced as well.

The LaTeX result contains "A \$k\$-ary ...", which produces literal
dollar signs, not math mode.

In contrast, "A \(k\)-ary..." works.

This happens with Org mode version 9.6.15 and with
9.7-pre (release_9.6.24-1336-gc8d133 @ ...).

Recipe:
emacs -Q
(add-to-list 'load-path "~/src/org-mode/lisp")
Then export an Org buffer/file with the above line:
C-c C-e h h
C-c C-e l l

Best wishes,
Jens

This is expected. The manual is not accurate here (and has been fixed on
development version of Org mode).
See https://list.orgmode.org/orgmode/f0597d96-a287-2c48-7897-6b8737c95217@posteo.eu/

This is also expected. Note that the latter syntax is preferred. We do
not recommend $k$ because it has edge cases like you encountered.

Canceled.
