[PEAK] Exception logging and source code encoding

There is a little problem with exception logging. I use new python2.3
feature for specifying default source code encoding for u"..."
unicode expressions (e.g. ISO-8859-2 in my case). Such expression can
occasionally be reported in traceback output. Then source code lines
are retrieved as 8bit string not as unicode and PEAK tries to convert
them to UTF-8 and that obviously fails because source lines can contain
character codes grater than 127. I have fixed this by following patch.
It is not very satisfactory solution but don't know how to correct it
better now. Original 'utf-8' encoding is good as unicode messages
are often sent to logger.
