For the benefit of those who may read only this far, it is NOT nice.

Could, but definitely shouldn't.

Some of the transformations are a little unfortunate :-(
0x00d0: ord('D'), # Ð
0x00f0: ord('o'), # ð
Icelandic capital eth becomes D, OK; but the small letter becomes o!!!
The Icelandic thorn letters become P & p (based on physical appearance), 
when they should become Th and th.
The German letter Eszett (00DF) becomes B (appearance) when it should be ss.
Creating alphabetics out of punctuation is scarcely something that 
bussiere should be interested in:
     0x00a2: ord('c'), # ¢
     0x00a4: ord('o'), # ¤
     0x00a5: ord('Y'), # ¥
     0x00a7: ord('S'), # §
     0x00a9: ord('c'), # ©
     0x00ae: ord('R'), # ®
     0x00b6: ord('P'), # ¶
