Bug 17180 – to!string('\0') makes "\0" which breaks concatination

import std.conv; import std.stdio; void main() { char c = 0; string s = to!string(c); writeln(`"` ~ s ~ `"` ); stdout.flush(); // the last quate GONE assert(s.length == 0 || s[0] != '\0'); } # We want one of these, at least. * Empty string * Alternative character or message * Raising an error

1) I see two quotes when I run your code. The last one is not gone. I'm running dmd 2.073.0 on Ubuntu linux. What version of dmd and what operating system are you on? 2) If there is a problem here, I don't think it's with to!string. For any char c, it returns a string [c]. Making '\0' an exception would be surprising. '\0' is a valid char, and "\0" is a valid string (with length 1).
