I have found the [http://www.unicode.org/Public/5.2.0/ucd/Index-5.2.0d2.txt data table], ([http://www.unicode.org/copyright.html#Exhibit1 license]), that is embedded in the Python module on-line. Should I split the task and have the stretch goal as a task on its own? (parse the table if needed, reverse a unicode string using the info from the table/an internal function with the combining info). --[[User:Paddy3118|Paddy3118]] 09:20, 28 July 2009 (UTC) |

About my addition: Yep, it's often tricky, and that's why I said "extra credit". The thing is, if you ''don't'' do it, you get nonsense from certain Unicode strings; this will become increasingly relevant as the world drifts away from the habits of ASCII-and-a-few-extras. So I added this to spread a little Unicode-handling-awareness. And that's why I think it shouldn't be a separate task: it's not a ''different problem'', it's ''more correctness'' (unless the string you're reversing is not really text, in which case you're looking for [[Binary_string_manipulation_functions|binary]] tasks). --[[User:Kevin Reid|Kevin Reid]] 12:03, 28 July 2009 (UTC) |

Extra Credit?
Does any example go for the extra credit Unicode combining characters? It seems to have been introduced [here] by Kevin Reid, but I am not sure that even his [E example] goes for the extra credit. --Paddy3118 04:35, 28 July 2009 (UTC)
- Nobody's tackled it since the requirement was introduced. It's moderately tricky too IIRC, as it gets into the whole problem of normalization of strings. —Donal Fellows 08:07, 28 July 2009 (UTC)
- I've cooked up something that works for the given Unicode string in Python and I have tried to make it generic, but the more I read about Unicode, the more I know I don't know :-) --Paddy3118 08:30, 28 July 2009 (UTC)
I have found the data table, (license), that is embedded in the Python module on-line. Should I split the task and have the stretch goal as a task on its own? (parse the table if needed, reverse a unicode string using the info from the table/an internal function with the combining info). --Paddy3118 09:20, 28 July 2009 (UTC)
