The purpose of the HELLO file is to demonstrate Emacs multilingual capabilities. It currently does this using iso-2022-7bit. Does this mean that UTF-8 is not the best coding system for multilingual texts in Emacs, because UTF-8 has some limitations (doesn't provide the proper font selection, loses cjk variants), so iso-2022-7bit is the preferable coding system for multilingual texts in Emacs? Is it possible to improve the UTF-8 support in Emacs since most files use it nowadays? -- Juri Linkov http://www.jurta.org/emacs/
