iPhone voice dictation is (still!) inserting [OBJ] characters since IOS 13.1.2

When I (and MANY others!) use voice input on iPhone to post on social media (usually Facebook, but others are reporting it elsewhere), there often is an object (looks like [OBJ] with a dashed line around it) inserted in the text. No one viewing the post from an iPhone can see this object, but anyone viewing it from a Windows web browser can definitely see it.

It appears to have first appeared iOS v13.1.2, but it is still occurring under IOS v15.6.1, so users have been enduring this craziness for over TWO YEARS. I only see this bug when I view a post made from iPhone on my Windows 10 web browser like Firefox. I can edit my post in my Windows web browser to remove the objects, but this is a tedious waste of time.

I would hope the social media programmers could filter out this [OBJ] character, but they appear to have no interest, and presumable are waiting for Apple to implement a resolution. I would love to see Apple put some energy into resolving this extremely annoying bug, even if it means working with 3rd party developers to eradicate it.
