You could try something like this. It works for accents. I 
haven't tested it on other characters yet.

import std.stdio;
import std.algorithm;
import std.array;
import std.conv;

enum
{
   dchar[dchar] _accent = ['á':'a', 'é':'e', 'è':'e', 'í':'i', 
'ó':'o', 'ú':'u', 'Á':'A', 'É':'E', 'Í':'I', 'Ó':'O', 'Ú':'U']
}

void main()
{
   auto str = "très élégant";
   auto removed = to!string(str.map!(a => (a in _accent) ? 
_accent[a] : a));
   writeln(removed);  // prints "tres elegant"
}
