ASP (VBscript) function to convert IDN-domains

I need a simple ASP-function that can convert from IDN-domainnames back and forth. Example:? räksmörgå[login to view URL] ->? [login to view URL] ->? räksmörgå[login to view URL] The functions should look like this: * toIDN(str) - converts to punycode * fromIDN(str) - converts from punycode Note: I need this in old ASP (VBscript), not .NET. ## Deliverables I just want to input the domain (eg: [login to view URL]) and get the same output, but converted (eg: räksmörgå[login to view URL]).
