this page claims to contain most common unicode characters, but they don't say how they made the list and i suspect it is not really a list of common symbols by measured frequency, also there's about 2000 characters, too many to include here: https://gist.github.com/ivandrofly/0fe20773bd712b303f78

https://stackoverflow.com/questions/5567249/what-are-the-most-common-non-bmp-unicode-characters-in-actual-use

" I would've expected the answer to be Chinese and Japanese characters used in names but not included in the most widespread CJK multibyte character sets, but on the project I do most work on, the English Wiktionary, we have found that the Gothic alphabet is far more common so far.

UPDATE

I've written a couple of software tools to scan entire Wikipedias for non-BMP characters and found to my surprise that even in the Japanese Wikipedia Gothic alphabet is the most common. This is also true in the Chinese Wikipedia but it also had many Chinese characters being used up to 50 or 70 times, including "𨭎", "𠬠", and "𩷶". "

(note: Gothic is for the most part a variant of the Greek alphabet)

" Emoji are now the most common non-BMP characters by far. 😂, otherwise known as U+1F602 FACE WITH TEARS OF JOY, is the most common one on Twitter's public stream...according to emojitracker.com ... I've been looking at statistics of text usage on the Web from the Common Crawl, by the way, and found that emoji are also the most common non-BMP characters on the Web now. They're not as common as on Twitter, of course. 😂 is still the most common one. "

" The answer is the mathematical letters. This past December I did a scan of the entire PubMed? Open Access corpus, and came up with these figures for astral characters in it.

The first number in the figures below is how many copies of each given code point I found in the entire corpus. First, though, to give you a notion on the relative frequencies, here are the top ten trans-ASCII code points in that corpus:

– ± − μ β α ° (the spaces in there are NO-BREAK SPACE, EM SPACE, HAIR SPACE)

And here now are the trans-BMP code points, in order of decending frequency:

"A zener card is a card containing one of five symbols: a circle, a cross, three wavy lines, a square, and a five-pointed star. Decks of zener cards were historically used to test for ESP."

some simple symbols:

circle triangle three lines (kinda like 三 i guess?) a capital L one line N, Z
