<div class="">However there is something else missing in the way the /Font dictionary</div>
<div class="">is built in that case, which prevents Acrobat from using that CMap.</div>
<div class="">The lack of encoding vector and /CharSet may well be the problem,</div>
<div class="">or it may be some other piece of font metadata that is needed.</div>

<div>complete — I leave that to you to finish :-).</div>
<div>It produces the attached PDF, from which you can Copy/Paste correctly.</div>
