Unicode characters are copied incorrectly on mac

[mymikemiller]

Clippy doesn't seem to play nice with unicode characters.

If I run:
await clippy.write('►');

And then paste, I get:
‚ñ∫

I expect to get:
►

I've only tried running this on a mac. pbcopy copies the character correctly, for example, in the terminal:
echo ►|pbcopy

And then paste:
►
