bug is actually in glibc
** Changed in: irssi (Ubuntu)
Status: New => Invalid
** Also affects: glibc via
http://sourceware.org/bugzilla/show_bug.cgi?id=5277
Importance: Unknown
Status: Unknown
** Summary changed:
- Infinite loop in irssi converting to ISO-2022-JP
+ Some conversions to iso-2022-jp can hang iconv
** Description changed:
- Binary package hint: irssi-text
-
- With irssi global settings:
- 04:43 recode_autodetect_utf8 = ON
- 04:43 recode_fallback = sjis
- 04:43 recode = ON
- 04:43 recode_out_default_charset =
- 04:43 recode_transliterate = ON
- 04:43 term_charset = UTF-8
-
- and a local channel /recode entry setting the channel to ISO-2022-JP, typing
"オマエモナー(=ﾟωﾟ)つ)ﾟ∀ﾟ)ｸﾞｧ" triggers a reproducable infinite loop deep in gconv:
