Sample file with the problem

When writing papers with mathematical notations, it is common to have equations and right after them add a non-blank character, f.i. a ")" parenthesis.

See attached DOCX file and notice that one of the equation is followed by a ")" which ends up being in the the next line. However, both the equation and the ")" should be together.

I tried adding a Word joiner to prevent the ")" from going to the next line, but it did not work. So I'm guessing this has something to do with how the Equation object is treated by the word joiner character.

I think Equation objects anchored "As Character" should be treated as characters when processing the Word Joiner.
