1928 variety of coding systems when reading a file and can translate back
1929 into any of these coding systems when saving a file.
1933 supports various "input methods", typically one for each script or
1940 to multibyte characters, coding systems, and input methods.
1954 An input method is a kind of character conversion which is designed
1955 specifically for interactive input.  In Emacs, typically each language
1956 has its own input method (though sometimes several languages which use
1957 the same characters can share one input method).  Some languages
1958 support several input methods.
1960 The simplest kind of input method works by mapping ASCII letters into
1961 another alphabet.  This is how the Greek and Russian input methods
1965 characters into one letter.  Many European input methods use
1971 The input methods for syllabic scripts typically use mapping followed
1972 by conversion.  The input methods for Thai and Korean work this way.
1978 they are handled specially.  First you input a whole word using

2108 chooses the Latin-1 character set.  In the .emacs file, you can do this
2109 with (set-language-environment "Latin-1").

2117 *** The command C-x RET c (universal-coding-system-argument)
