There may be made implementations,, however its quite standard in programming libraries, which most of software development people are supposed to use. One of the good starting point may be https://docs.oracle.com/javase/7/docs/api/java/net/IDN.html 2) Is there a test suite that can be used to test Punycode converters? I think, if ACE can be converted back to same Unicode is good test. And almost all online converters<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Feai.xgenplu...> provide bi-directional of Unicode<->ACE. People can try tool<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Feai.xgenplu...> and [Mark Svancarek] I think if you use one tool to convert in one direction and another tool to convert it back, and get the same result, then you know they are implementing the same rules – but not whether it’s the rules set that you prefer (idna2003 vs idna2008, for instance). 3) Would the source of input (typed, cut/paste, input from a data file) make any difference? This probably has to do with RTL scripts Bad Input can make a difference, this is true for every application. While dealing with RTL, there are some more rules to be followed and its related to input, may not be alone relevant for punycode. [Mark Svancarek] I once personally experienced errors when cutting/copying RTL text out from a LTR UI and then into a different LTR UI… I didn’t investigate to determine if the error happened during the cut operation or during the paste operation. Anecdotally, I hear this is fairly common, and should be reported as a bug. In contrast, cut/copy/paste errors within a fully RTL user experience (as an Arabic or Hebrew user might commonly encounter) is supposedly pretty reliable. Thanks.
