Whether to attempt to clean up UTF-8 data for XML output: remove invalid sequences and characters. Should be Yes if XML output (eg. result style 8) is used (and Storage Charset should be empty). This helps avoid browser errors with XML pages. Note: if XML output is not being used, this should be set to No, as certain characters that are HTML-safe but not XML-safe will be removed if enabled.
