Parallel is having trouble handling quotes for unicode characters

[Glen Huang]

Hi,

Parallel is having trouble handling quotes for me. If I run

parallel echo \"'{}'\" ::: 你好 世界

I get \?\?\?\?\?\? back.

My mental model for this cmd is that echo "你好" and echo "世界" would be pass to 
the subshell, and it should print those characters without problem. But given 
the maturity of this project, I guess I probably did something wrong. I wonder 
how could I prevent the garbling of text? I'm using GNU parallel 20170222

I have to use quotes because my real use case involves something like this

export start="你好"
parallel -a file name=\"'${start} {}'\"';' curl -o /dev/null 
\"'$url/$start/$name'\"


Any help is much appreciated.

Regards
Glen
