2353  *   The bug we are compensating for is that some drongo at Microsoft
2354  *   used lpHeaderInfo to pass binary data to CommitUrlCacheEntryA.
2355  *   As a consequence, CommitUrlCacheEntryA has been effectively
2356  *   redefined as LPBYTE rather than LPCSTR. But CommitUrlCacheEntryW
2357  *   is still defined as LPCWSTR. The result (other than madness) is
2358  *   that we always need to store lpHeaderInfo in CP_ACP rather than
2359  *   in UTF16, and we need to avoid converting lpHeaderInfo in
2360  *   CommitUrlCacheEntryA to UTF16 and then back to CP_ACP, since the
2361  *   result will lose data for arbitrary binary data.
