You said writing system, nothing about phonetic correspondence. But then I'll simply replace English by Spanish. There's of course the silent h which throws a spanner in the works sometimes, and there's the v/b overlap, but extremely easy to pronounce straight from the text, even without understanding. And with 27 letters that don't combine with others into groups, a lot easier to learn than Hangul.

Or Inglish with a speling riform? Det shood bi sooparizi too lurn es wel. End yoo get ol da books end moovis for fri.

Anyway, you haven't replied why you think it's advantageous. All that trouble just to avoid translating here or there, or learning multiple languages? What makes you believe that speaking the same language makes a better place?
