use "to!string(c);". Any help?

if you are trying to avoid GC allocations this is not what you 
want.

    dchar c = '\u03B3';

    string s = "";
    s ~= c;

    writeln(s);
    writeln(s.length); // please aware of this

Some useful things:

string is immutable(char)[]
wstring is immutable(wchar)[]
dstring is immutable(dchar)[]

if you have a char[]:
you can convert it to a string using assumeUnique:

import std.exception: assumeUnique;

char[] ca = ...

string str = assumeUnique(ca); // similar for dchar->dstring and 
wchar->wstring
