example code:
----------
// ß

/**

import processing.pdf.*;

when having two different types of comments before an import statement and
one of the comments contains non-ascii characters the following error occurs:

i forgot: this seems to be new to processing version 1.1

Fixed; please verify.

sorry, can't verify because i cannot build an updated application. the
"./make.sh" described in the howto.txt doesn't work for me.
