Request parameters as unicode Strings?

[Bjoern]

Hi,

sorry if this question is yet again very noobish... I am developing a
small app for Google App Engine and I noticed that request parameters
seem to be of type str. Is there a way to make them all be unicode by
default? Not sure if the problem lies with App Engine or bottle.py

Thanks!

Request parameters are byte strings because URLs are byte strings.
Neither Bottle nor AppEngine are in a position to guess or force an
encoding. If you need the values as unicode, you have to explicitly
encode them and catch encoding errors in your app code. I'd use a
decorator to do that.

def unicodeparam(encoding):
def decorator(func):
def wrapper(**kargs):
for key in kargs:
kargs[key] = kargs[key].decode(encoding)
return func(**kargs)
return wrapper
return decorator

(untested)

Thanks - somehow I never encountered this before... Will look into the
decorator pattern, not yet sure how it is applied in Python web
services.

My parameters are multipart-formencoded, but it is true, the browser
does not seem to send a specification of a charset along.
