Two Sputnik tests fail on the JSC interpreter when encoding a two-byte unicode character (\u2028), but pass on the JSC JIT:

From testing on desktop interpreter builds, I'm no longer seeing functional differences to the JIT.  This is likely predominantly due to replacing PCRE with YARR, along with other recent bug fixes.
