How do I type an accented letter in VSCode?

On Windows, entering special characters (including letters with accents) can be done with ALT Codes. Pressing down the Alt key and then a specific series of numbers on the num pad will type the corresponding character.

e.g.

• Alt+233 = é
• Alt+225 = á

On OSX, the method is a bit simpler: https://support.apple.com/en-us/HT201586

Typing special characters on Linux is a bit hairy...
