D identifiers are UTF8 encoded. The compression done for Win32 uses the 
same byte range as UTF8 (>= 0x80) to encode repeated name segments. 
Combining both produces an undecipherable mess.

The linker just spits that out, the decompression/demangling should be 
aware of these possibly invalid encodings.
