I noticed in one of your questions that you own 3D software. Have you got QuickFont as part of it? in that case have a look at the Burgues free font -see link. you can use their preview option and type in the desired letters. If they are what you are looking for download the font and use QF to convert it to an embroidery font. Let us know how that works for you.
This is what it would look like.
Hmmm, I tried to Google "Burque Font" and found nothing...the only thing it brought up was "Burgues Font"...would that be what you are looking for?
I noticed the Burgues font can be downloaded free from one site and from another an extended version costs just under €100, but that offers the most beautiful flourishes. Expensive for just 3 letters. Both are open type, which does not always work well in every software.
Here is a free font converter which can convert OTF to TTF to be more compatible with software...
