As you can see the attached screen shot, new editor has problem displaying double-byte characters.
Double-byte characters seem to be treated as single-byte characters therefore the right-half character overlaps to the next character.
Old editor doesn't have this issue.

        Looks like a cosmetic issue that doesn't affect compilation?

        Yes, it is a cosmetic issue and no problem to compile.
