Digitizing True Type Fonts (Arabic Glyphs)

[Asarkon]

Using Tajima DG/ML Pulse 14 (Maestro Ed.)

I'm trying to digitize as a beginner from Arabic True Type Fonts on my system. I'm noticing that there are two problems:

The letters appear split when first imported, though I use this website to copy the lettering so the letters show up using the correct justification.

The 2nd problem is I have to set the spacing to -2 for the letters to stick together as a word and even then for some fonts the letters will appear to close together.

In the attached image I would like to understand if this a gap between the letters and if it will sew with the same density as others or will there be an obvious split of letters (which is not wanted) and if so how to fix that.

Thanks
