Composition operator ∘ is different from ◦ (\circ)

[pablosanjose]

If I type \circ<tab> in latest master (also checked in 0.5) under macOS it produces a different Unicode character (◦) than the one used for function composition (∘).

julia> (cos◦cos)(0) #written using \circ<tab>
ERROR: UndefVarError: cos◦cos not defined
julia> (cos∘cos)(0) #copy-pasting ∘ from the manual

It is new for 0.6 (#17155) so it shouldn't work on 0.5.
Also, I get the expected behaviour on master (and 0.6 release branch):

julia> (cos∘cos)(0) # with \circ<TAB>

You are totally right, my apologies. This was due to an undesired interaction with another program (Typinator)
Closing! (blush)
