用Wininet API读取的Unicode网页内容为乱码

[woshishagua]

代码：
hSession = InternetOpen("vb wininet", 1, vbNullString, vbNullString, 0)
hInternet = InternetOpenUrl(hSession, sUrl, vbNullString, 0, IF_NO_CACHE_WRITE, 0)
iResult = InternetReadFile(hInternet, sBuffer, BUFFER_LEN, lReturn)
sData = sBuffer
InternetCloseHandle hInternet
InternetCloseHandle hSession

(sUrl的网页，charset为UTF-8，用IE浏览时，编码选择为Unicode可正常显示中文，选择成GB2312会出现乱码)

现在用上述代码，得到的sData里的中文都是乱码，比如"媒体"会变成"濯掍綋"
即使用StrConv转换也没有：sData = StrConv(sData, vbFromUnicode)

有没有谁知道这是什么原因？
谢谢

不晓得,帮忙顶

是不是buffer的大小的问题

[woshishagua]

与Buffer的大小没有关系，我用Inet1.OpenURL(..)得到的结果同上面一样

up,偶也遇到这个问题

把 UTF-8 转化为 unicode

API返回的可能是ASC码，需要转化一下。
