Based on those numbers I gathered some stats about keyboard layouts:
* 18% of all characters are symbols, 12% are spaces and 70% are alphabetic
* 20% of all non-space characters are symbols and 80% are alphabetic.
* US kb layout users need to use shift for 64% of symbols
* Finnish/Swedish kb layout users need to use shift for 73% of symbols and AltGr for 7% of symbols.
* Fi/Swe layout users thus need to use 25% more modifer keys for symbols.
Conclusion: Fi/Swe layout sucks.
