In one of its unit tests the DEL character (127) is used. According to std.ascii.isControl this is a control character, but not according to std.uni.isControl. This will cause the test suite for the pull request not to be run since std.json chokes on the DEL character.

I don't know about control characters, but std.json doesn't handle UTF-16 surrogate pairs in strings, which are legal JSON.  I *think* it does properly handle the 32 bit code points though.
