Bye,

You could also use appender. Appender supports it:
//----
import std.array, std.algorithm, std.stdio;
void main()
{
dchar[3] d = "日本語";
string s = "I speak ";
auto app = appender(s);
app.put(d[]);
writeln(app.data);
}
//----
That said, I'd suggest to not pass an array to appender when
building it: the current implementation makes a lot of
assumptions about the state of its internal buffer, which end up
being wrong when you pass an array as above. These assumption can
lead to some potentially very nasty effects, including plain old
segfault.
Today, I'd suggest instead writing it as:
//----
import std.array, std.algorithm, std.stdio;
void main()
{
dchar[3] d = "日本語";
string s = "I speak ";
auto app = Appender!(string)();
app.put(s);
app.put(d[]);
s = app.data;
writeln(s);
}
//----
Doing this is safe.
