You can use JvGetStringUTFRegion().  See the CNI docs:

(Strictly speaking, this method produces a char* encoded as UTF-8.  That's only
one way to convert Unicode to a C string.)

They are the internal names for `jchar' and `jbyte', respectively, which are the
same size as the corresponding Java types.  (These and other types are defined
in javaprims.h.)
