from rapidjson:
Query String
In addition to GetString(), the Value class also contains GetStringLength(). Here explains why:
According to RFC 4627, JSON strings can contain Unicode character U+0000, which must be escaped as "\u0000". The problem is that, C/C++ often uses null-terminated string, which treats \0 as the terminator symbol.
To conform with RFC 4627, RapidJSON supports string containing U+0000 character. If you need to handle this, you can use GetStringLength() to obtain the correct string length.
For example, after parsing the following JSON to Document d:
{ "s" : "a\u0000b" }
The correct length of the string "a\u0000b" is 3, as returned by GetStringLength(). But strlen() returns 1.
GetStringLength() can also improve performance, as user may often need to call strlen() for allocating buffer.
Besides, std::string also support a constructor:
string(const char* s, size_t count);
which accepts the length of string as parameter. This constructor supports storing null character within the string, and should also provide better performance.
