Unexpected input, duplicated characters.

• [x ] I am on the latest Hyper.app version
• [x ] I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name:
• Hyper.app version: 3.0.2
• Link of a Gist with the contents of your .hyper.js:
• Relevant information from devtools (CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere):
• The issue is reproducible in vanilla Hyper.app: yes

Issue

When trying to type ~/ on a portuguese keyboard laybout
~ : is done with by just pressing ~^ key
/ : is done with SHIFT + 7

Expected was to output :

~/

the output is :

//

also everytime I try to use "~" it just duplicates the next character, for example if I do "~" and then "t" the output is "tt".

I can avoid this issue only if I use space between inputs, example: "~", "SPACE", then "/" I the output is "~/" of course "~" shows up first.

I'm using git for windows but the same happens if I use default values aka Vanilla.

Start by reproducing the duplicated-character behavior in vanilla Hyper with a Portuguese keyboard layout, using the DevTools entry point mentioned in the report. Compare input for ~/ and ~ followed by t with the expected output, and consider the issue done when those sequences render correctly without requiring a space.
