Hmm. What aspect of caching do you want us to document? FYI, Org mode has been doing various forms of caching since forever. Recently, we just employed a bit more regular API and introduced one more kind of caching - parser cache. In addition to the previously existing image cache, publishing cache, ID cache, clock cache, etc. > Please also make sure that the code which actually writes the data to > the cache files makes a point of binding coding-system-for-write to a > proper value (probably utf-8-unix), or forces > buffer-file-coding-system of the buffer from which it writes to have > such a safe value, to avoid annoying and unexpected prompting of the > user to select a proper encoding.

I believe that this particular problem has been solved in https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=c8f88589c It is a part of Org 9.7. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
