Can't show unicode in IntelliJ, vim and other places.

In IntelliJ using Java if I try this statement:

System.out.println("\u26f7" + "   " + "\u1f3c3");

It only displays the first unicode character, the one one is shown as a rectangle. I tried to print the second one as "\uD83C\uDFC3" but it still didn't work.
I am thinking it's a problem with the system but I don't know what it could be.
I'am sorry if this is a stupid question but I remember in installation of uncommenting "en_US.UTF-8" in /etc/locale.gen and writing "LANG=en_US.UTF-8" in /etc/locale.conf. Is UTF-8 the wrong thing to use?

Re: Can't show unicode in IntelliJ, vim and other places.

Most likely you are just lacking a font (or configuration for the programs/terminal in use to use such font) that provides those glyphs.

But lets start with locale information, please post the output of the following:

locale -a
localectl

Then what fonts have you installed?  I'd prefer to focus on the chacters not showing in vim as I have no idea how IntelliJ works.  What terminal emulator are you running vim in and what font(s) have you configured the terminal to use?

Re: Can't show unicode in IntelliJ, vim and other places.

locale-a:

C
en_US.utf8
POSIX

localectl:

   System Locale: LANG=en_US.UTF-8
       VC Keymap: n/a
      X11 Layout: n/a

I use adobe-source-code-pro-fonts.
I use st as terminal emulator. To be honest I haven't look much into st configuration, I use it as stock because it works for me. I just looked and it has this line:

static char *font = "Liberation Mono:pixelsize=12:antialias=true:autohint=true";

So I suppose I use Liberation Mono in st.

The problem appears everywhere. For example, take these 3 unicode characters:
https://unicode-table.com/en/1F6B4/
https://unicode-table.com/en/1F3C3/
https://unicode-table.com/en/26F7/

When I paste then in vim I get this:

As you can see only the last one shows. But the issue is the same if I do it in IntelliJ, or in chromium(only the last link shows the symbol).

Re: Can't show unicode in IntelliJ, vim and other places.

I don't get the symbol for any of those three.  I gather those glyphs are not covered by many fonts.  If you want to use them, you'll need to ensure you use a font that covers that unicode range.

Based on the coverage map your best bet would be unifont, but that may not even provide all of those.
