special.ttf symbols

[LyesSaadi]

Hello 😀!

Who you gonna call when there's a licensing issue with a font? Ghostbusters! Me 😛!

Anyway, still on my quest to get this packaged in Fedora, I'm looking again into special.ttf!

• \android: Let's begin with this symbol. Using my amazing detective skills, I scoured through the archive, went through the files, entered the matrix, hacked Nasa's website with HTML and just simply typed android svg font on DuckDuckGo to determine that it probably came from here. The issue is that this website doesn't really seem to be reliable when checking submission's licenses, and using a Google Reverse image search point to other duplicates, most with a proprietary license, which is not really great... So, I need to ask if it was really from there or from somewhere else? Also, as I'm typing this @sp1ritCS is trying to redo the image on Inkscape.
• \TeX: It's a bit weird not using the standard TeX symbol (it's apparently from AndroidLaTeXMath)? But, do you remember what font is that?
• \texteuro: I can't find the origin of this glyph, and it's probably from a Debian font according to calitexman (jlatexmath), but he can't remember. Unfortunately, as the killjoy that I am, that is not enough 😛! Are you open to me swapping it with another font's Euro symbol? URW Bookman's euro symbol is quite similar, for instance.
• \textmu: This is the euro symbol, but it shouldn't be? Is this a bug?
• And, most importantly, crucial to this entire project, what will decide of the fate of this world, which may bring death or eternal happiness on this land: Are you the one to have drawn the magnificent, the superb, the incredible, the absolute, the unique and the holy \parallelogram? This piece of art is indeed the essence of this whole project. No, to be serious, that seems quite silly, but I still need to make sure of whether you drew it yourself or if it is from somewhere else 😛!

Anyway, I'm going back to hide in the shadows until my master, © Copyright™, calls for me again.

@sp1ritCS recreated the Android icon.
I swapped \texteuro & \textmu by their appropriate glyphs from lmroman10.
I recreated the font to remove the weird bits (like the \texteuro & \textmu glyphs being linked or the undefined glyphs at the end).

We get this as a final Copyright Notice (Note that @sp1ritCS is still not sure about the license of his Android icon recreation):

I just need the confirmation about the Licenses of the TeX characters' fonts and the sacred parallelogram.

And we get this as a result with the new special.ttf (screenshot from NoteKit):

And for comparison with the old special.ttf:

Sorry for the late response... 😅

Yes, the parallelogram glyph was created by me 😄 and the cute robot was from Google's Android logo (I can't remember where I found it though...), and the TEX was from Google fonts if I recall correctly, but I can't find it anymore with the attempts of keywords 'android', 'robot', 'machine' and so on to search it.

I believe the day to deprecate these fonts (it is a mess to manage these fonts) is not far (again, please take a look at the openmath branch, although it is not complete, and now only can be compiled by CMake).
