NewStringUTF not working with ISO8859-13 (latvian)

We have this small test that takes a string which is on Latvian and it prints just fine on the C side. Once we pass this string to the Java side using NewStringUTF it just prints question characters instead (?). After researching this matter we have seen that some people are sugesting to use the Jstring constructor with a byte array. We tried that but it core dumps. Apparently (from what I have been reading in the newsgroups) this seems to be a bug in the VM. Does anybody have a solution to this problem?
