Incorrect source mappings because of certain (Unicode?) characters in comments

[rajeevgopalakrishna]

Certain characters (or scripts) in Solidity comments appear to cause incorrect source mappings.

For example, in 0x06012c8cf97bead5deae237070f9587f8e7a266d_KittyCore.sol, the symbol that looks like underscore in "email_protected":

Similarly, the Asian characters in below comments from 0x5d0d76787d9d564061dd23f8209f804a3b8ad2f2_FoMo3Dlong.sol also cause source mapping problems:

        uint256 plyr;   // pID of player in lead， lead领导吗？                                                                
        uint256 team;   // tID of team in lead                                                                                 
        uint256 end;    // time ends/ended                                                                                     
        bool ended;     // has round end function been ran  这个开关值得研究下

	uint256 keys;   // keys

	uint256 pot;    // eth to pot (during round) / final amount paid to winner (after round ends)                          
        uint256 mask;   // global mask                                                                                         
        uint256 ico;    // total eth sent in during ICO phase                                                                  
        uint256 icoGen; // total eth for gen during ICO phase                                                                  
        uint256 icoAvg; // average key price for ICO phase                                                                     
    }

It seems to be fixed with #252 (merged in master/dev). @rajeevgopalakrishna can you confirm it?

[rajeevgopalakrishna]

Yes, confirm that this is fixed in contracts I have tested so far.
