https://issues.dlang.org/show_bug.cgi?id=15710 Issue ID: 15710 Summary: Replacement for std.utf.validate which does not throw Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: issues.dlang jmdavisProg.com For whatever reason, std.utf.validate throws when a string is invalid Unicode rather than returning true or false (probably because it was easier at the time it was implemented, since the only wwy to validate Unicode other than reimplementing decode would have been to catch the exception it threw on failure). It also only works on strings and not arbitrary ranges of characters. So, we need a new function (e.g. isValidUnicode) which validates a range of characters and returns whether it's valid Unicode rather than throwing. Then we can deprecate validate and get that much closer to getting rid of UTFException and all of the extraneous Unicode validation that we have right now. --
