|
|
* As a consequence, CommitUrlCacheEntryA has been effectively

|
* that we always need to store lpHeaderInfo in CP_ACP rather than
|
|
* in UTF16, and we need to avoid converting lpHeaderInfo in
|
|
* CommitUrlCacheEntryA to UTF16 and then back to CP_ACP, since the
|
|
* result will lose data for arbitrary binary data.
