Mathematical Operators (U+2200 - U+22FF)

If you want to report (to your friend, mommy, wife, luver, cat... whomever) what characters are not displayed properly, just refer to the UA, URI and character number. Something like following:

User agent (yours):

CCBot/1.0 (+http://www.commoncrawl.org/bot.html)

URI tested (this page):

http://orwell.ru/test/Unicode/math/test?font=Code2000

Not displayed character(s) (sample only):

1-16; 28, 29, 159-200, 249, 256.

In most cases, you should see all characters except 243-256 (page source - decimal: 8946-8959). From listed fonts, only Code2000 contains them.

So, if you want to make any math-web-page using HTML only and desperately need to declare CSS font-family, I'd recommend the next one (as on 2004-02-15):

CSSClass { font-family: Code2000, "Arial Unicode MS", "Lucida Sans Unicode"; } /* (!) Generic family omitted. */

User agent:

Not displayed character(s):
