Support displaying invalid UTF-8 in language-environment-specific ways. 2008-08-05 Aidan Kehoe <kehoea@parhasard.net> * specifier.el (current-display-table): Initialise this here, not in x-init.el, since we want it even on non-X builds to use the support for displaying Unicode error sequences according to the current locale. * mule/mule-cmds.el (set-language-info): Document error-sequence-coding-system, used to describe how to display characters that are not valid Unicode on disk. * mule/mule-cmds.el (finish-set-language-environment): Implement error-sequence-coding-system. * unicode.el (unicode-error-sequence-warning-face): New face, to make it possible to distinguish invalid Unicode sequences from the characters given by the valid Unicode sequences. * mule/cyrillic.el ("Russian"): ("Ukrainian"): ("Bulgarian"): ("Belarusian"): ("Cyrillic-ALT"): Add support for error-sequence-coding-system for all these languages. * mule/latin.el: Add support for error-sequence-coding-system for the Latin-alphabet language environments.
