Trying out this program but I find it does not honor custom encoding. When setting up a network for example I set custom encodings and set all three to ISO-2022-JP. When I enter the channels I see garbage characters. If I try /charset ISO-2022-JP that does not work either. This is 0.4.0. I have also tried this on other networks like say rizon then joining #japanese which is an ISO-2022-JP channel. Remember in networks I am setting custom encoding and setting all three to ISO-2022-JP. Of course konversation, xchat etc. work correctly. If I join a utf-8 Japanese channel quassel does display Japanese characters correctly but without iso-2022-jp the program is unusable for me. I am operating KDE 4.2 on 64 bit Gentoo Linux. This also applies in show channel list etc. like on when all 3 custom encoding are set to iso-2022-jp many channel names are garbage characters (the channel names are encoded in iso-2022-jp and are Japanese characters).

I tried this with the gentoo ebuild (compile from source) x64 precompiled nightly binary listed on this site and gentoo ebuild from repository (did a checkout of source and compiled). I also tried connecting with a windows client on a work machine to the linux core server.

Could you please tell us where we can test this?
You said someting about a channel called #japanese, but on which network?

#3 Updated by EgS almost 15 years ago

Thanks to some mild poking in the eye from seezer, I managed to figure the network out ;)

Reproduced the issue.

Assigning to Sput, as it seems to be an issue with the UTF-8 autodetection.
Perhaps we should disable the UTF-8 detection in some cases.

Thank you for looking at this. I am sure dealing with UTF-8 autodetection must be difficult.

BTW there are some iso-2022-jp channels on freenode like #wikipedia-ja-articles #wikinews-ja #wikipedia-ja-vandalism yet others are UTF-8 like #gentoo-ja or #nihongo is a good test I think as it is a Japanese IRC server with some channel names, MOTD etc. in iso-2022-jp and I think all channels on that network are encoded iso-2022-jp. If it is down it is joined with

Yes #japanese is in iso-2022-jp and has a decent amount of activity. It is joined with #japanese on but sometimes too much English I think.

Just wanted to say I consider disabling UTF-8 autodetection as EgS suggests seems the easiest solution.

Quassel 0.7.1; same problems. =/
Gentoo x64. whines

#9 Updated by khris over 12 years ago

I agree with salyavin's opinion. It's a simple and easy solution that disabling UTF-8 auto-detection as an feature.

Guessing encoding is a over enginieering for UTF-8 auto detection bugs. And multibyte encoding is not only japanese codecs but also korean's and chinese's too.

Just confirming that this still exists in 0.8.0...

This really is a pretty big bug. It makes chatting in any channel using iso-2022-jp absolutely impossible.

Perhaps the priority of this bug should be bumped up, since it breaks the core function of quassel, chatting?

Fixed'ish in PR 7 ; I added a blacklist of codecs which should bypass the detection. Testing showed that EUC-{JP,KR} and Shift-JIS worked fine, so I only added ISO-2022-JP to the blacklist. If others are wrongly detected, please nudge me.

This is still not resolved as of 0.10.0 on both client and core. Attempting to set is-2022-jp via the network configuration UI results in it syncing with the core and then displaying default values again, disregarding the set values. Some other unusual behaviour is also exhibited with other random encoding selections, but not all of them.

Can anybody replicate this?
