1)Mime message have content type neither a 'text/plain' nor a  
'text/html', but ussually 'multipart/mixed' and some others. AND this  
patch puts charset only for the content type with a charset inside  
'content type' header, i.e. for 'text/plain' and 'text/html' !
2)If you are sending just text/plain than Apache adds defaultcharset  
itself, as I know
3)User offten cant change charset at the browser  (for exaple me)when  
you are using window without toolbars and menues. Sic!
4)About rare or nor rare cases. Now it is very offten when  
autogenerated mail goes "Content-encoding: 8bit" with not latin1 and  
so on with first 7bit chars. Ask more people from not latin alphabet  
countries.
5)" Save as" is not the best solution, but it works.
