It is already throwing an exception called
core.exception.UnicodeException. This even provides you the index where
decoding failed.
(However Phobos is not using it, AFAIK.)
-----------
import core.exception, std.stdio, std.conv;
void main() {
char[] s = [0x0f, 0x12,0x34,0x56,0x78,0x9a,0xbc];
try {
foreach (dchar d; s){}
} catch (UnicodeException e) {
writefln("error at index %s (%x)", e.idx, to!ubyte(s[e.idx]));
// error at index 5 (9a)
}
}
-----------
