Having done some digging, I've found at least one reliable way to
reproduce the issue with -Q:
1. launch Emacs using `emacs -Q';
2. switch to *scratch* if not there already;
3. do M-x column-number-mode RET;
4. paste the following Persian text into *scratch*:
ویکیپدیا دانشنامهای اینترنتی با بیش از ۲۸۰ زبان با محتوای آزاد است که با
همکاری افراد داوطلب نوشته میشود و هر کس که به اینترنت دسترسی داشته باشد
میتواند مقالههای آن را ویرایش کند.
It is from the first sentence of the "دربارهٔ ویکیپدیا" (About
Wikipedia) section on <https://fa.wikipedia.org>.
The text should appear garbled. However, if you omit step 3, the
pasted text should appear just fine. It appears that if Persian text
is pasted before column-number-mode is enabled, even if the paste is
subsequently undone before enabling column-number-mode, the issue
does *not* surface.
The above works for pasting into a message-mode buffer as well. I have
not tried to find a recipe specific to gnus-article-mode yet.
Hope this helps.
P.S. if I did not mention earlier, all of this is on a Debian Buster
GNU/Linux system.
