DOCUMENT:Q294831 15-AUG-2002 [iis] TITLE :Server.HTMLEncode/Server.URLEncode Corrupt High UTF8 Characters PRODUCT :Internet Information Server PROD/VER::5.0 OPER/SYS: KEYWORDS:kbCOMIS kbWin2000PreSP3Fix kbWin2000sp3fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Services version 5.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When an Active Server Pages (ASP) script uses the Server.HTMLEncode or Server.URLEncode method, if the session codepage is set to UTF8, the data on certain strings may appear corrupted or garbled. CAUSE ===== This problem occurs because Internet Information Services (IIS) 5.0 assumes two bytes per character, and some UTF8 characters use three. This creates a buffer that is too small. RESOLUTION ========== The following fix allocates additional buffer when the initially allocated buffer size is insufficient. To resolve this problem, obtain the latest service pack for Windows 2000.
