Option-Space Keyboard Combination

Define an abbreviation in a snippet expander like Typinator or KM. (Typinator comes with a little AppleScript that lets you insert every character by its decimal Unicode name. For example {Scripts/Unicode.applescript 8239} gives you a Narrow No-break Space.)

Keyboard Maestro token processing supports unicode hex numbers.

As a general rule, you can't type them, they have to be pasted.
