+Under X Windows, you can determine which fonts provide a particular Unicode
+character using fc-list from the fontconfig package.  For example, if your
+friend complains that the emoji you sent won't display, run fc-list with the hex
+value of the character to determine which font your friend should install.
+
+$ fc-list ':charset=0x1F4A1'
+/usr/local/share/fonts/noto/NotoColorEmoji.ttf: Noto Color Emoji:style=Regular

+$ pkg which /usr/local/share/fonts/noto/NotoColorEmoji.ttf
+/usr/local/share/fonts/noto/NotoColorEmoji.ttf was installed by package noto-emoji-2.042_1
