Cannot compare equality of tiny_utf8::basic_string and tiny_utf8::iterator #79
Description
I get a compile error in test_manipulation.cpp line 101 when I attempt to run the tests (specifically, EXPECT_EQ(res1, str.end());). I tried to add additional operator overloads in tinyutf8.h, but without success.
This is on macOS with Clang 17.0.0 using the C++ versions configured in the project's CMake.
