digitalmars.D - diet-ng 1.8.3: source/diet/internal/html.d:185: data modification

The actual modification happens in the line marked as `(1)`. But 
this is not the location of the root cause.

The variable `ch` is of type `dchar`. Does anybody see the 
problem?

```d
     switch (ch) {
		default:
			if (flags & HTMLEscapeFlags.escapeUnknown) {

				dst.put(to!string(cast(uint)ch));
				dst.put(';');
			} else dst.put(ch);
			break;
		case '"':
			if (flags & HTMLEscapeFlags.escapeQuotes) dst.put("&quot;");
			else dst.put('"');
			break;
		case '\'':

			else dst.put('\'');
			break;
		case '\r', '\n':
			if (flags & HTMLEscapeFlags.escapeNewline) {

				dst.put(to!string(cast(uint)ch));
				dst.put(';');
			} else dst.put(ch);
			break;
		case 'a': .. case 'z': goto case;
		case 'A': .. case 'Z': goto case;
		case '0': .. case '9': goto case;
		case ' ', '\t', '-', '_', '.', ':', ',', ';',

			 '%' , '{', '}', '[', ']', '`', '´', '$', '^', '~':
			dst.put(cast(char)ch); // <<----- (1)
			break;
		case '<': dst.put("&lt;"); break;
		case '>': dst.put("&gt;"); break;
		case '&': dst.put("&amp;"); break;
	}
```

I was going to say that these are all ASCII characters, but it appears 
that the '´' has slipped in there erroneously (0xB4, outside of the 
ASCII range).
