There was originally an attempt to prescribe rather than to recommend the interpretation of ill-formed 8-bit Unicode strings. It may even briefly have been an issued prescription, until common sense prevailed. I do remember a sinking feeling when I thought I would have to change my own handling of bogus UTF-8, only to be relieved later when it became mere best practice. However, it is not uncommon for coding standards to prescribe 'best practice'. Richard.
