skystrife / cpptoml

With some g++ (version 5.3.0) I got this warning:

/home/jmlemetayer/development/misc/cpptoml/include/cpptoml.h: In static member function ‘static std::__cxx11::string cpptoml::toml_writer::escape_string(const string&)’:
/home/jmlemetayer/development/misc/cpptoml/include/cpptoml.h:3063:26: warning: comparison is always true due to limited range of data type [-Wtype-limits]
             else if (*it >= 0x0000 && *it <= 0x001f)
                          ^

This is raised by this line:

cpptoml/include/cpptoml.h

Line 3063 in 2051836

else if (*it >= 0x0000 && *it <= 0x001f)

g++: Comparison is always true
