-With this environment variable, you can specify
-the native character set you are using. You must be able to display
-this character set on your terminal.
-.PP
-This variable is checked to see if a RFC 2047 header field should be
-decoded (in
-.BR inc ,
-.BR scan ,
-.BR mhl ).
-This variable is
-checked by
-.B show
-to see if the
-.I showproc
-or
-.I showmimeproc
-should
-be called, since showmimeproc will be called if a text message uses
-a character set that doesn't match
-.BR $MM_CHARSET .
-This variable is
-checked by
-.B mhshow
-for matches against the charset parameter
-of text contents to decide it the text content can be displayed
-without modifications to your terminal. This variable is checked by
-.B mhbuild
-to decide what character set to specify in the charset
-parameter of text contents containing 8\-bit characters.
-.PP
-When decoding text in such an alternate character set,
-.B nmh
-must be able to determine which characters are alphabetic, which
-are control characters, etc. For many operating systems, this
-will require enabling the support for locales (such as setting
-the environment variable
-.B $LC_CTYPE
-to iso_8859_1).

.B mhbuild
will assume the character set is of the type given by the
-environment variable MM_CHARSET. If this environment variable is not
+standard
+.IR locale (1)
+environment variables. If these environment variables are not
set, then the character set will be labeled as \*(lqx-unknown\*(rq.
.PP
If a text content contains only 7\-bit characters and the character set
this content, it checks if your terminal can display this character
set natively.
.B mhn
-checks this by examining the environment
-variable
-.BR $MM_CHARSET .
-If the value of this environment variable is equal
+checks this by examining the current character set defined by the
+.IR locale (1)
+environment variables.
+If the value of the locale character set is equal
to the value of the charset parameter, then
.B mhshow
assumes it can
-display this content without any additional setup. If this environment
-variable is not set,
+display this content without any additional setup. If the locale is not
+set properly,
.B mhshow
will assume a value of \*(lqUS-ASCII\*(rq.
If the character set cannot be displayed natively, then
.B Scan
will only decode these fields if your
terminal can natively display the character set used in the encoding.
-You should set the MM_CHARSET environment variable to your native
-character set, if it is not US-ASCII. See the mh-profile(5) man
-page for details about this environment variable.
+You should set the appropriate
+.IR locale (1)
+environment variables to your native
+character set, if it is not US-ASCII. See
+.IR locale (1)
