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: [email protected]

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.
