Unicode consortium already manages a ton of language specs. If there's any group of folks I'd trust to understand languages (natural or otherwise), it's them.
This is the one. Think of all the "misconceptions developer have about X" lists, I trust Unicode to have encountered (if not written) all of them. The people behind unicode are thorough.
