There are also
  ≔ COLON EQUALS U+2254
and others.

No problems using such characters in Flex:

The problem is the lack of input methods. 


No problem for me: I can input a ← by typing either Alt Gr + 4 (on the numeric keypad) or compose +  < + -
I have no way to type "colon equals" but to type it as compose + : + = I should simply add one single line to my ~/.XCompose file:
<Multi_key> <colon> <equal> : U2254
and restart my text editor. That isn't more difficult than that.

(I'm on my phone right now.)
