Usage: charset-hook alias charset
Usage: iconv-hook charset local-charset
The charset-hook command defines an alias for a character set.
This is useful to properly display messages which are tagged with a
character set name not known to mutt.
The iconv-hook command defines a system-specific name for a
character set. This is helpful when your systems character
conversion library insists on using strange, system-specific names
for character sets.
