On the other hand, running the same statement via rcall() seems to work fine.

julia> "α;" |> rcall
"!#03b1;"

julia> ans |> RExpr

α

In the meantime, calling a similar statement can make my REPL stuck indefinitely.

julia> "αα;" |> rcall

# no response

The text was updated successfully, but these errors were encountered:

A bit more testing:

julia> R"α"

α

julia> R"αα"
Error showing value of type RExpr:

Unicode characters are very tricky to support, there is a bit of functionality for it built in, but I don't have the time available to make unicode support more robust. ASCII is recommended.

tomyun · 2020-06-20T06:03:30Z

That sounds fair. By the way, I came across with your old conversation on this issue and a workaround mentioned there seems to work for me.

julia> codepoint('α')
0x000003b1

julia> "!#03b1;;" |> rcall |> RExpr

α

julia> "!#03b1;!#03b1;;" |> rcall |> RExpr

αα

julia> R"!#03b1;"

α

julia> R"!#03b1;!#03b1;"

αα

Is this the same bug? It completely breaks Reduce ...

Have you tried using Reduce.Reset() to reset the REDUCE instance?

No, I just restarted Julia.
