For the record, the actual representation of strings in Mercury
is implementation-dependent.  Although the C and assembler back-ends
of the current Mercury compiler do use null-terminated sequences of bytes,
the Java and .NET back-ends do not; those back-ends use a representation
which is capable of storing strings that contain embedded null characters.
