(process) UNIXProcess.java.solaris has non-ASCII characters in it

The J2SE source file

src/solaris/classes/java/lang/UNIXProcess.java.solaris

contains non-ascii characters. Because the default encoding is ascii,
the byte sequences in this source file that represent non-ascii characters
cannot be decoded properly bu a java compiler without specifying
-encoding iso8859-1 on the javac command line.

Incidentally, the problem occurs in a French-language copyright notice
that is quite out of date. The best fix would be to remove the French
copyright notice and update the English one.

We expect to add a new warning in the 1.4.2 javac compiler to
detect and report these source encoding errors. See 4767128.
