What is the char for the lock glyph?

There's a lock character in the image for Fira Code.

Where can I find a list of all chars and their description?

See https://github.com/ryanoasis/powerline-extra-symbols#glyphs
Only first row has a wide support, other fancy symbols (like “flame”) may be or may be not available in fonts.

Also you could check https://www.nerdfonts.com/.

I'm pretty much only using Fira Code.
