This issue is not with response.flash but with request.args. The characters
allowed in args are fairly restrictive -- here are the regexes used:
http://code.google.com/p/web2py/source/browse/gluon/rewrite.py#51,
http://code.google.com/p/web2py/source/browse/gluon/rewrite.py#575.
In the LOAD() examples, try setting ajax=True and the flash should work.
