Copy encoding flags when copying a regex [Bug #20039]
* :bug: Fixes [Bug #20039](https://bugs.ruby-lang.org/issues/20039) When a Regexp is initialized with another Regexp, we simply copy the properties from the original. However, the flags on the original were not being copied correctly. This caused an issue when the original had multibyte characters and was being compared with an ASCII string. Without the forced encoding flag (`KCODE_FIXED`) transferred on to the new Regexp, the comparison would fail. See the included test for an example.
