From cpp/poppler-global.h header:

class POPPLER_CPP_EXPORT ustring : public std::basic_string<unsigned short>
{
public:
    ustring();
    ustring(size_type len, value_type ch);
    ~ustring();

    byte_array to_utf8() const;
    std::string to_latin1() const;

    static ustring from_utf8(const char *str, int len = -1);
    static ustring from_latin1(const std::string &str);
...
}
