I think there is a room for improvement here. In my opinion the message
is too confusing for newbies. It would be easier for them if there is a
mini tutorial available about what's going on with links to other more
broad tutorials (like unicode tutorial). Instead of generic error
--
UnicodeDecodeError: 'ascii' codec can't decode byte 0xa5 in position 0:
ordinal not in range(128)
--
It can be like this. Notice special url, it is pointing to a
non-existing :) tutorial about why concatenating byte strings with
unicode strings can produce UnicodeDecodeError
--
UnicodeDecodeError: 'ascii' codec can't decode byte 0xa5 in position 0:
ordinal
not in range(128)
For additional information about this exception see:
http://docs.python.org/2.4/exceptions/concat+UnicodeDecodeError+str

Here is the sample code how it can be done:
---
extended_help = {
("concat", UnicodeDecodeError, str, unicode):
"http://docs.python.org/2.4/exceptions/concat+UnicodeDecodeError+str";,
("concat", UnicodeDecodeError, unicode, str):
"http://docs.python.org/2.4/exceptions/concat+UnicodeDecodeError+str";
}
def get_more_help(error, key):
if not extended_help.has_key(key):
return
error.reason += "\nFor additional information about this exception
see:\n "
error.reason += extended_help[key]
def concat(s1,s2):
try:
return s1 + s2
except Exception, e:
key = "concat", e.__class__, type(s1), type(s2)
get_more_help(e, key)
raise
concat(chr(0xA5),unichr(0x5432))
