VSConstants::VsTextBufferUserDataGuid::VsBufferDetectCharSet_guid Field

bool: If true and the current BufferEncoding is CHARFMT_MBCS, the buffer runs its HTML charset tag detection code to determine a codepage to load and save the file. The detected codepage overrides any codepage set in CHARFMT_MBCS. This is forced on in the buffer's IPersistFileFormat::LoadDocData when it sees an HTML type of file, according to the extension mapping in $RootKey$\Languages\File Extensions.
