Irssi/UTF-8

In der Shell-Config (z.B. .zshrc):

export LC_CTYPE=de_DE.UTF-8 
export LC_COLLATE=de_DE.UTF-8
export LC_TIME=de_DE.UTF-8
export LC_NUMERIC=de_DE.UTF-8
export LC_MONETARY=de_DE.UTF-8
export LC_MESSAGES=C
export LC_PAPER=de_DE.UTF-8
export LC_NAME=de_DE.UTF-8
export LC_ADDRESS=de_DE.UTF-8
export LC_TELEPHONE=de_DE.UTF-8
export LC_MEASUREMENT=de_DE.UTF-8
export LC_IDENTIFICATION=de_DE.UTF-8

In der .screenrc:

defutf8 on

und in irssi:

/set term_charset UTF-8
/set recode_autodetect_utf8 ON
/set recode_fallback UTF-8
/set recode ON
/set recode_out_default_charset UTF-8
/set recode_transliterate ON
save

Funktioniert problemlos z.B. auf shell.uugrn.org mit einem MacOS 10.5.6 Client und Terminal.app.
