MobileRead Forums - View Single Post - strange invisible? character

stumped · 12-12-2018, 11:06 AM

so I recently posted about an issue with calibre content server not giving me recent tweak of a specific book.
what led to this is that in this book, after any scene break, I am seeing a strange artifact in Moon reader. I see the letters OBJ surrounded by a square of dashes forming a border.
I see nothing at all in calibre or sigil editors to account for this
but when I view the book in adobe digital editions, I see an X inside a square as the strange character.

messing with scene breaks was a try at removing stuff that might cause it but no joy

so I have an "invisible" character at those points in the epub, now how can I edit it out ?
invisible in sigil, invisible in calibre editor, visible in ADE, visible in notepad ++, visible in Moon reader
NB if i paste it into MS word, I see the same artifact as in Moon reader i.e. OBJ inside of a border

in calibre editor I see e.g.
<p class="x03-co-body-text">The ...

with nothing untoward about that class

but when I paste a snippet into notepad++ I see the "invisible" character as a thinck horizontal dash with dotted lines above and below. the strange character is after the > and before the T in the above example
so there is definitely something there, but how can I edit it away if I cant see it in the editor.
i could probably write some regex to work on the 1st character after that specific x03 class as that's always where it happens, But I am curious as to what it is and why it is there ?
