      Reaching into the absl internals is dangerous.
      It's unnecessary in this case, and should be avoided.

      + #include "mongo/platform/bits.h"
...
getCodePointLength
-    return absl::base_internal::CountLeadingZeros64(~(uint64_t(charByte) << (64 - 8)));
+    return countLeadingZeros64(~static_cast<unsigned char>(charByte)) - (64 - 8);
 }
