Article ID: 294831 - Last Review: November 21, 2006 - Revision: 3.1 Server.HTMLEncode and Server.URLEncode Corrupt High UTF8 CharactersThis article was previously published under Q294831 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.
