There has been talk at the IETF of redefining IDNA2008 (the current way you prevent issues like this) in terms of the PRECIS framework (RFC 7564). This wouldn't exactly "solve" the problem, but it would mean that IDNA could be more agile with respect to Unicode versions and would make it easier to react to new problems, new confusable characters, etc. as they happen.
