Hi Enrico,

I tested the script and there are two points:

1. "_string_summary_size" is undefined

2. I do not know if "return s.encode('utf-8')" is tcorrect. What 
encoding is the lldb stdout?
     I registered the wstring_SummaryProvider for std::string also and 
get wrong results.

     std::string aString = "HÄLLÖ WÖRLD!!!";
     std::wstring aString32 = L"HÄLLÖ WÖRLD!!!";
     unsigned short pRawString[] = {'H', 0xc4 , 'L', 'L', 0xD6, 'W', 
0xD6, 'R', 'L', 'D', '!', '!', '!', 0 };
     std::basic_string<unsigned short> aString16 = pRawString;

     (lldb) frame variable aString
     (std::string) aString = "HÃ?LLÃ? WÃ?RLD!!!"
     (lldb) frame variable aString16
     (std::basic_string<unsigned short, std::char_traits<unsigned 
short>, std::allocator<unsigned short> >) aString16 = "HÄLLÖWÖRLD!!!"
     (lldb) frame variable aString32
     (std::wstring) aString32 = "HÄLLÖ WÖRLD!!!"

     Maybe thats an stl or compiler issue. When registering the 
wstring_SummaryProvider for wstring and 16bit strings only everything is
