// Since UTF-32 is not supported:
//  * HTML resources will use the parent encoding (windows-1252)
//  * XML resources will default to UTF-8
// ... except for the UTF-32LE-with-BOM case, where the UTF-32
// BOM will be mistaken for a UTF-16LE BOM (FF FE 00 00), in which
// case it will be interpreted as UTF-16LE.
