Is it possible to add a symbol to the character map?

Recently I saw a Darwinfish decal on the back of a car. This was new to me (I lead a sheltered life) and I included the image in a note to a friend.
I had looked quickly in the character map without luck, but found an image easily enough on line.

However this left me wondering: does the character map include all the Unicode symbols? For instance, I tried Control-Shift-U269C and it gave me a fleur-de-lis, which I do not see in the character map.

If new ones are created, do they arrive with the updates? If not, if one encounters a new one, can it be added to the existing map?

Do all Linux distributions use the same map? I am using Linux Mint.

Every font has its own selection of characters. In the word processor, using the Insert-Special character item in the menu will show just the characters in the selected font. In the character map program from the main menu, you can see all the characters available in your selection of fonts. The fleur-de-lis is in the miscellaneous symbols section and on my computer it's in DejaVu Sans Mono.

Fonts will be updated now and then, but a distro may not rush to give you the latest one: not many people will be anxious to get their hands on a fleur-de-lis or a black flag.

You can learn about what's available and where things are at

If you want to add your own characters to a font, get the Fontforge editor.

with a little luck, a unicode character exists for your darwinian fish.

draw it and find out!

edit: i like it. but due to its complexity, i doubt there'll be a unicode character for it.

font management looks in all fonts available on the system until it finds the character requested.
that's why your char displays although it is not contained in the current system font.

this is beyond including the character in an email, but if a unicode character does not exist, youmight want to look at various symbol fonts (old windows' *dings, or fontawesome and the like for modern webdesign)

Complexity does not seem to be an obstacle, if you look at the Dingbats Fonts on 1001freefonts. I have not been able to localize a Darwin-fish, though.

There is a Darwin Font available on and MyFonts but it is commercial. If someone has this font, she/he could take a look on the symbols in the “Private Use Area” (U+E000) and those for special characters. But I doubt that there will be any interesting symbols at all.

OK, thanks.
It is reassuring to be reminded what a fractal world it is—I will never have an excuse to be bored, and I will never lack an excuse to put off real work!
