Support charset "ks_c_5601-1987"

Reported by Sungjoo Ha | November 13th, 2013 @ 08:15 PM

Many Korean emails are sent with charset="ks_c_5601-1987".
I don't think this is currently supported by MailMate and MailMate will display garbage instead of properly encoded Korean.
This charset could be interpreted as EUC-KR or CP949. (Refer to http://lists.kde.org/?l=kde-i18n-doc&m=100396886120761&w=2)
Please fix this.

    I would love to do that. Could you send me an example message?

    I use the iconv library to do conversions. Apparently it should support all of the above:

    iconv --list | egrep -i 'ks_c_5601-1987|EUC-KR|CP949'
ISO-IR-149 KOREAN KSC_5601 KS_C_5601-1987 KS_C_5601-1989 CSKSC56011987
EUC-KR EUCKR CSEUCKR
CP949 UHC

    It'll be easier to debug with an example. I've also seen issues with some Japanese messages (which required workarounds).

    I'm attaching a part of a raw message. Also, refer to the attachment file current.png and correct.png. If you look carefully, you'll notice that the English characters are shown correctly, while the Korean characters are shown incorrectly.

    Fetch the latest test release by holding down ⌥ when clicking “Check Now” in the Software Update preferences pane. Then you should get r3842.

    Let me know whether or not it fixes the issue. I simply replace ks_c_5601-1987 with euc-kr to get around a limitation in the iconv library. It seems to work for me although I do not read Korean.

    Note: Messages already fetched by MailMate unfortunately needs to be re-fetched using “Message ▸ Reset...”.

    I can see that the body of mail is properly converted, but the subject and the sender name isn't.
    Perhaps you could try to convert the subject and the sender name as well?

    You missed the note I believe:

    Did you try this?

  • Sungjoo Ha

    Sungjoo Ha November 15th, 2013 @ 03:21 PM

    You are right. I did miss the note and indeed it works now. Thank you.
