fixed: in static size_t WideToInt(const wchar_t * wide_string, size_t string_len, int & z, bool & correct)
we didn't test UTF8_CheckRange()
added: functions for converting from a wide string into an utf8 c-string:
bool WideToUTF8(const wchar_t * wide_string, size_t string_len, char * utf8, size_t utf8_len, size_t & utf8_written, int mode = 1);
bool WideToUTF8(const wchar_t * wide_string, char * utf8, size_t utf8_len, size_t & utf8_written, int mode = 1);
bool WideToUTF8(const std::wstring & wide_string, char * utf8, size_t utf8_len, size_t & utf8_written, int mode = 1);
bool WideToUTF8(const wchar_t * wide_string, size_t string_len, char * utf8, size_t utf8_len, int mode = 1);
bool WideToUTF8(const wchar_t * wide_string, char * utf8, size_t utf8_len, int mode = 1);
bool WideToUTF8(const std::wstring & wide_string, char * utf8, size_t utf8_len, int mode = 1);
