I made a test to reproduce the error described in onivim/oni2#1554

  describe("CommandLineError", ({test, _}) =>
    test("simple command line", ({expect}) => {
      let _ = reset();
      input(":");
      expect.int(CommandLine.getPosition()).toBe(0);

      input("e");
      expect.int(CommandLine.getPosition()).toBe(1);

      input(" ");
      expect.int(CommandLine.getPosition()).toBe(2);

      input("<Left>");
      expect.int(CommandLine.getPosition()).toBe(1);

      expect.int(Array.length(CommandLine.getCompletions())).toBe(20);
    })
  );

The output got from previous test is the following

SUMMARY: AddressSanitizer: negative-size-param /build/gcc/src/gcc/libsanitizer/asan/asan_interceptors.cc:476 in __interceptor_strncpy

I will try to submit a PR if I manage to solve

I've been trying to edit text in Swedish with oni2 and noticed that sometimes the cursor was being shown incorrectly when jumping by word or even searching with / or ?. The reason seems to be that every swedish character adds an extra offset to the cursor position. This is also a problem in visual mode and when highlighting searches:

This offset gets returned from native code, and unfortunately I don't understand much of C code, but I ended up in e.g. normal.c: https://github.com/onivim/libvim/blob/master/src/normal.c#L4534 (in case this helps).
