Translate for chars to strings

[Andrej Mitrovic]

There's a really useful function 'translate' in std.string, used like this:

__gshared dchar[dchar] MangleTable;

shared static this()
{
    MangleTable =
    [
        '*':'p',  // ptr
        '&':'r',  // reference
        '<':'L',  // left angle
        '>':'R',  // right angle
        ' ':'_',  // space
    ];
}

string mangleType(string input)
{
    return input.translate(MangleTable);
}

However I'm looking for something which translates characters to
strings. Of course that also implies potential reallocation. Does
anyone have such a function in some library?

Note that I'm not looking for .mangleof, I need to work on strings of
C++ names, not D symbols.
