On Windows, there exist at least two APIs for dealing with the Registry: The Win32 API (RegCreateKeyA, RegCreateKeyW, etc.) works with null-terminated ASCII or UTF-16 strings. The native API (ZwCreateKey, etc.), on the other hand works with UTF-16 strings that are stored as buffers+length and may contain null characters. Malware authors have been relying on the Win32 API's inability to
