Windows 7, This issue has been present for quite a while. I have checked the Region and Languages settings and they are not the same as
Boxes show for the angle brackets which markup idioms in the LEB.
If I use a special unicode font (only a limited few on my system - Arial UnicodeMS, Lucida Sans Unicode and the default L4 fonts) then this box will not appear. If I use any other font then these boxes appear for this particular markup in this one resource. All other symbols in other resources work great for many more fonts that these above.
I would like to request for consideration using a different symbol for this particular markup so that more fonts would be available to use as the default font. Currently, I am using Segoe UI - a Microsoft system font.
Thanks for giving us the opportunity to place requests for consideration.
