<p class="MsoNormal">Hello John and Herbert, </p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I greatly appreciate your replies to my queries about some difficulties I was having using the Lucida font for the first time. Your replies pointed me in the right direction and answered all my questions.</p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Particularly helpful was referring me to the unicode-math documentation, which helped me to resolve many of the issues. </p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Learning about the unicode-math options <span style="color:black">[bold-style=ISO,math-style=ISO] helped a lot.</span></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Here’s my latest and hopefully last MWE and its output, which is attached as a PDF document. Perhaps my investigation may have some results of interest to you. <span style="color:black">The bottom line is that item (6) together with the
unicode-math ISO options provide the best method to get bold math characters in the correct typeface. It turns out that my desiderata (bold, italic math symbol with bold upright subscript) are ISO standards. </span></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Thanks again.</p>

<p class="MsoNormal">I am new using the Lucida OT fonts and have been testing them. Thanks to Bruno Voisin, the fonts are correctly installed on my M1 MacBook Pro running OS 12.3.1. I’m using MacTeX 2022 with TeXShop 4.72. I have correctly typeset all the Lucida
source documents that are included in the Lucida distribution.</p>

<p class="MsoNormal">2. Same text printed in emphasis and italic mode are identical.</p>
