Direction Change Glyphs

In Accordance I'm exporting to RTF a section of parsed Hebrew text with the Unicode preference selected. When I import the RTF file into Mellel it displays as Lucida Grande. When I replace the style with SBL Hebrew small directional arrows are inserted (and print) whenever there is a change in direction. For example, on each line there is some Hebrew and some English text. The Hebrew is R->L and the English is L->R, whenever there is a change in direction it is marked by a small elevated arrow.

J. P. Kang (in the Accordance forum) said: "I took a look at the SBL_Hbrw.ttf font and saw that it actually has glyphs for the Right-to-Left Mark (x200F) and Left-to-Right Mark (x200E), whereas most other Unicode fonts do not have entries for them (since they should really be invisible). This explains why these arrows appear only with SBL Hebrew."

I can delete the glyphs and/or replace them with tabs (which usually, but not always, works). Is there anything else I can do so that these glyphs don't display?

Thanks, Karyn

Karyn and I discussed this via email, but the information might also be of interest to others:

This problem is due to Mellel displaying glyphs for some control characters, in this case right-to-left and left-to-right markers. Normally, the visual representation of control characters should be supressed unless the user opts to view them for editing purposes. Mellel used to display all control characters, so this problem was also seen with the zero-width joiner and non-joiner characters. The makers of Mellel corrected this problem for ZWJ and ZWNJ, but evidently not for all control characters. I will try to contact the Mellel developers to discuss this with them.
