Interesting characters in the font, but it is not clear which one

Question

Design

I use Font Awesome for icons, but the Opera browser sometimes mangles characters and displays the wrong thing.
Once again, observing such a picture, I noticed interesting symbols, and the question arose about their origin. I did not find it in Font Awesome, in Tahoma, which is also the main one on the page (although it is huge).
Actually, here is an example of what was received:


Cloud icons and Adobe Reader are of particular interest, are they in standard fonts (Tahoma in particular)?
(Of course, I found snowmen and smileys-pirates there, but still there are doubts)

Answer 1

The icons were found by chance, these are Octicons from GitHub .
How they got to my page I have no idea, but it's them.
If someone has ideas, I will be glad to listen, and no one will fix it for sure.

Answer 2

Excuse me if I say stupidity, but still, did you find the font exactly as an image? Is it impossible to inspect an element on a page and find out the name of the font?
I can advise a good resource with the ability to assemble a certain set of icons into a font - fontello.com/
Just mark the necessary icons and download the finished archive with fonts. Here, by the way, the choice is much richer than Font Awesome.
There are also social icons like twitter, gmail, vk, github, as well as icons of various services - dropbox, picasa ...
Unfortunately, I did not find anything hinting at file formats, but there are quite a lot of clouds there.
Perhaps it will help.
