The 0xe2 byte thing sounds like a non-ASCII character sneaked into in
the file with the code. In your email the transposition sign after the ]
looks suspicious, but after sending via email anything can happen.
As always it could be useful to know your gretl version, platform, and
how the new Kalman code was installed, if not with gretl itself.
