Do you happen to use any sort of special symbol ?
For example, dialogs are usually shown "with those" or, if you copy paste from some Word-like document, with something ressembling two triangle lacking one side and pivoted away from the text.
Yet I know from experience that on the ARchive using them, either the simple or the double, simply cut away the rest of your text after it.
I discovered it some long time ago when trying to make a certain smiley.
Obviously, I can't use it to show you what symbol I'm talking about, and I'm on mobile so no screenshots, but it's the one used for the eyes in this :
except pivoted 90 degrees.
