1. I am not a lawyer.
2. Without knowing where you are (& thus what jurisdiction you're in), what your 'hobby projects' are & what exposure to the public they have, I think it would be difficult to give an informed opinion.
3. If your hobby projects are non-profit & only get seen by your family & friends, it's hard for me to see how you would get into trouble.

Note that it is currently taking about 1 year (!!!) for new fonts to be reviewed & published by the team here (I'm not a member of the team, I just read the forum sometimes).

@misteradvizer: 1. IF you determine that your modifications are within the terms of the relevant licences, and you can't find someone else to do them for you, you could consider doing them yourself with some font-editing software - I imagine it should be pretty easy to copy-paste characters from one font into another one in something like FontForge (which is free).
2. I think claudeserieux means to say "the problem is money"

You could try contacting BlamBot directly - in my (limited) experience, font makers are often glad to talk to people who are genuinely interested in their work.

Note that it seems to be taking more than 9 months for new font submissions to be reviewed.

I can't get a good match with any of the software I use! Maybe it's a custom-made font that hasn't been released publicly? (If you're keen, you could make your own version!)

No worries.
My answers to your questions:

"Is there anybody can do it?" - yes, there are many people who can do it, but what are the terms & conditions (free/paid/timeframe/KPI)? You could potentially do it yourself, especially if you only want 5 glyphs - there are good programmes (free & paid) available that could greatly assist (see the Tools/Software page here at Dafont for a start https://www.dafont.com/soft.php ).

"does anyone know if the font Scrypticali is based on some else" - I don't know, but it looks like original work to me; probably the only person who knows for sure is Sami/SDFonts, and they aren't available.

Given that their most recent font appeared on Dafont just over 17 years ago (in October 2005), and that all your efforts thus far have come to nought, I think it's extremely likely they have left the font-creating scene, and you will be left stuck as you are now.

Font-identifing software gives me the following candidates: various fonts called 'Copperplate' or similar, 'Antique Half Block', 'TR Schubert'.
No free fonts though!

Suggest you try searching "how to install font on iPad".
You can get articles (like this https://www.howtogeek.com/350438/how-to-install-fonts-on-an-ipad-or-iphone/),
official help (like this https://support.apple.com/en-au/guide/ipad/ipad952422ba/ipados),
and even videos (like this https://www.youtube.com/watch?v=T3rsyx601ag).

Did it get published, or did you just submit it?
If you just submitted it, it's taking 9 months or more for fonts to be reviewed & published (I'm not an admin, just a user).

I'm able to edit the human-readable name after I've entered the Font ID, not sure why you can't, sorry.

@Phantom Creative Studio & JDStudio: I am not an admin of Dafont, but I have seen elsewhere in this forum that it is taking 9+ months for fonts to be reviewed & published after submission. I suspect (but do not know) that this is because of the very large number of fonts being submitted.

@hishand studio: I am not an admin of Dafont, but I have seen elsewhere in this forum that it does not take the same length of time for a font to be published after resubmission (& the problems are corrected) - only a few weeks, if my memory is correct.

@Indra:
no, not to authors, to Dafont itself

Hi All,
I like Dafont & think it's one of the best font sites around (thanks Dafont!)- so much so that I'm happy to make a small donation to show my appreciation. I do the same for other sites that I really like e.g. Wikipedia, so why not Dafont?
Does anyone know if such a thing is possible and/or would be appreciated?

@letterey:
They've probably considered it - but if it's true that it's currently taking about 9 months for submitted fonts to be reviewed, they would have to disable it for the same length of time (9 months) to catch up! They must have a backlog of thousands of fonts!
In fact, I'll do a little maths...
9 months is very close to 40 weeks;
if we say they're approving 300 fonts per week, and rejecting 50 (probably much more),
40 x 350 = 14,000 !!

I'll just finish by saying a big "Thank you" to the hardworking people at Dafont for all their work!

I mean Dafont is receiving so many submissions every week that they can't keep up. I've just seen someone say that it's taken 10-11 months for their font to be reviewed!!

Apparently the site is so inundated with new fonts that it is currently taking 6-8 months for them to get approved!

I'm guessing because it's a free site and literally hundreds of fonts are getting submitted every week (goodness knows how many get rejected)

I'm 99% sure there is no notification if the font is rejected. I have no idea how long they are taking to publish/approve new fonts at present - does anyone else know?
