Hands-on Rust: Redundant use of "emoji" (page 13)

Pg 13 on Unicode support redundantly mentions emoji twice. Suggest removing the “and emoji” in the first part and keeping the “It even works with emoji”

It supports Unicode, and emoji. “Привет, мир”, or “ こんにちは世界” are valid string literals that you
can print. It even works with emoji.

Thanks for the bug report. I’ve logged it in the issue tracker, I’ll do my best to get that fixed up in the next beta release. I think I tried to include an emoji example and discovered issues with using them in the print system - that paragraph can definitely be cleaned up.
