OK, so in Unicode you have these special characters\*, combining characters. When you put a combining character after another character, it alters it. For example, U+0301 "COMBINING ACUTE ACCENT" ( ́) will put an accent on the previous character (like é).
\*not "special characters" as in "printing chars" vs "special chars" special characters, if you're familiar with that.

There are some characters, the regional indicator letter characters, which act like combining characters. Here's U+1F1E6 "REGIONAL INDICATOR SYMBOL LETTER A": 🇦
When you type them next to eachother, you'll get a flag. Here's U followed by S: 🇺🇸
Your computer probably displayed that as the US flag.
I did some research and the flags in the titlebar are of the codes VE, GB, and VE. The flags in the tab in Firefox are of the codes UA, ??, and UA, where ?? is a flag I don't recognize. [2/]
@bartavi For the ?? flag, maybe it's "Flag of the Trust Territory of the Pacific Islands", the flag of "Yap", or the flag of "Chuuk State"? https://en.wikipedia.org/wiki/List_of_flags_by_color_combination#White,_blue
