What does all those letters I see mean? I see only flags of France, Germany and the UK. Maybe it has to do something with fonts installed on my computer.
The Unicode symbols for flags consist of a special set of combining country-code letters that when used in two-character combinations compose into flags. That solution ensures that the Unicode standard doesn't hard-code the existing list of countries and country codes. In addition to future-proofing, that also avoids dealing with disputed regions that not everyone recognizes as countries.
When I imagine, in my head, "hmm, how can I present a string of 20 x 2 chars, what is the best way I can confuse the reader?" this is the exact solution I come up with, also.
