unicode - Console does not show 4 bytes utf-8 -

i'm using ubuntu. console (using python or bash) not print utf8 chars of 4 bytes, 3 bytes or less.

example (bash):

eran@eran-ms-7788:~/dropbox/help$ echo -e "\xee\x8c\xb0" # prints v sign eran@eran-ms-7788:~/dropbox/help$ echo -e "\xf0\x9f\x8f\x80" # should print basketball sign not print 

i same python console.

any way solve this?

most called unicode fonts implement characters present in unicode bmp (basic multiligual plane) - u+0000 u+ffff, can represented using 3 bytes using utf-8.

there few fonts implement characters beyond bmp: is, u+010000 u+1fffff (which encoded using 4 bytes in utf-8), , think linux console or terminal no exception. because of this, not see character expect. on time, possible support characters beyond bmp become better, take long time. can read more here.
