Of course, the encoding is the real challenge, since tengwar isn't included in unicode. If you have the patience for LaTeX and thus not actually typing in tengwar, but instead stuff like /Toore/TTthreedots/TTdorbelow, you can get very precise layout with the TengwarScript LaTeX package (https://ctan.org/pkg/tengwarscript?lang=en)
Many believe that Meta is using an embrace, extend, extinguish strategy here. See:

I've done only a little experimenting with bright inks, but it seems like unless the nib is quite broad the color gets lost. This now has me hunting for inexpensive stub nibbed pens :)
I haven’t done much of it. I have another Pilot Metropolitan with a medium nib which writes very smoothly. The stub nib isn’t as smooth, although my initial experiments have been on paper that’s not especially fountain pen friendly.
I also notice that I have to write more slowly with the stub nib or I get line widths that vary unexpectedly. Pilot calls it a calligraphy nib and I think it really is, rather than something you’d use for everyday notetaking. Perhaps those whose handwriting is more consistent have better results.
It’s too bad because I very much like how stub nibs let colored inks show. I’ve noticed that with narrow nibs, sometimes a colored ink doesn’t really “read” as colored when you look at it.
