Hi, Do guys still need it? Actually it happened on the keyseed.py but not the duckhunter.py.
And so far I just found two messed-up key-sets.
1: In American English Language, the _ (underscore) is a - (hyphen).
2: In British English Language, the @ (At) and ' (apostrophe) are in reverse, means you type @ it becomes ', you type ', it becomes @.

So I just made a little change to the keyseed.py, and now should be working fine.

You can test it and if you find any other messed-up key-set, you may post it here, I may want to give it a fix.
