MANCONV(1) Manual pager utils MANCONV(1) NAME
manconv - convert manual page from one encoding to another SYNOPSIS
manconv -f from-code[:from-code...] -t to-code [-dqhV] [filename] DESCRIPTION
manconv converts a manual page from one encoding to another, like iconv. Unlike iconv, it can try multiple possible input encodings in sequence. This is useful for manual pages installed in directories without an explicit encoding declaration, since they may be in UTF-8 or in a legacy character set. If an encoding declaration is found on the first line of the manual page, that declaration overrides any input encodings specified on man- conv's command line. Encoding declarations have the following form: '" -*- coding: UTF-8 -*- or (if manual page preprocessors are also to be declared): '" t -*- coding: ISO-8859-1 -*- OPTIONS
-f encodings, --from-code encodings Try each of encodings (a colon-separated list) in sequence as the input encoding. -t encoding, --to-code encoding Convert the manual page to encoding. -q, --quiet Do not issue error messages when the page cannot be converted. -d, --debug Print debugging information. -h, --help Print a help message and exit. -V, --version Display version information.
