FM11 and ITC Zapf Dingbats Std Medium Font

My office recently upgraded from Structured FrameMaker 8 | Win XP to  Structured FrameMaker 11 | Win 7. We also upgraded some fonts, including Zapf Dingbats. We have replaced Zapf Dingbats with ITC Zapf Dingbats Std Medium.

We use an automated process to create the formatted FrameMaker files that involves importing xml feeds into FrameMaker templates. The  Zapf Dingbats font was used to create stars and to create square bullet. In order to create the stars, in the xml code we used the letter “H”. The code looked like this:
<row>
<tabletext><emphasis role="stars">HHH</emphasis></tabletext>
<tabletext><emphasis role="stars">HHH</emphasis></tabletext>
<tabletext><emphasis role="stars">HHHHH</emphasis></tabletext>
</row>

After the imported was completed, the xml “H” displayed as a solid star.

After replacing Zapf Dingbats with ITC Zapf Dingbats Std Medium, the imported data displayed with “?” marks instead of stars. I replaced the “H”s with the following tag: &#x2605;:

<row>
<tabletext><emphasis role="stars">&#x2605;&#x2605;&#x2605;</emphasis></tabletext>
<tabletext><emphasis role="stars">&#x2605;&#x2605;&#x2605;</emphasis></tabletext>
<tabletext><emphasis role="stars">&#x2605;&#x2605;&#x2605;&#x2605;&#x2605;</emphasis></tab letext>
</row>

This code displays the solid star.

Is it possible to generate the solid star using the “H” or is it necessary to use the &#x2605;?

I encountered a similar issue with the square bullet. In order to generate the solid squares, I needed to replace the Autonumber Format code In FrameMaker 11 paragraph designer from:
\n\t

To:
■\t

I also changed the code in the EDD from:
Autonumber format: \n[\t]

To:
Autonumber format: ■[\t]

Is it possible to generate the solid square using the “\n” or is it necessary to use ■?
