The problem here is HDN_ENDTRACKW that's sent instead of expected
HDN_ENDTRACKA. Initial notification format is set correctly to NFR_ANSI on
control creation, but it gets overridden later with HDM_SETUNICODEFORMAT. So
this line in listview.c is questionable:

---
    /* set header unicode format */
    SendMessageW(infoPtr->hwndHeader, HDM_SETUNICODEFORMAT, TRUE, 0);
---

This is quite an old line (10 years), added with commit 07a308d6. We probably
can't do that with header, cause ListView window could be set to NFR_ANSI by
its parent and the same parent listens to header notifications in the same
format.
