Re: [evolution-patches] Patch to enable Thai TIS-620 charset in Evolution 1.4.x

[Kitt Tientanopajai <kitt gear kku ac th>]

Hi,

TIS-620 _is_ 8-bit charset. Well, it's 7-bit actually since the standard body defines only second-half of 8-bit table (#128-#255). The full 8-bit table for Thai is ISO-8859-11. It's just that many applications recognize TIS-620, but not ISO-8859-11. Thai users also refer/recognize TIS-620 but not ISO-8859-11. So, I just follow this.  All Thai linux distro. define alias for these anyway. 

OK, I've just test Evolution 1.4.5 again with 
- clean installation / _no_ patch applied
- newly-created user account (to ensure those Gconf things)
- and, LANG=th_TH 

These are what I got:
- Evolution can display incoming Thai message (TIS-620 encoded) correctly when setting View -> Character Encoding to 'default'  or in Mail Preference -> Message Display -> Default charset encoding is _blank_ or set to Other/TIS-620.
- For outgoing mail composed in Evolution, if Composer Preferences -> Character set is _blank_, mail content will be UTF-8 encoded. with content-type:charset in mail header set to _null_. I can just set charset in the composer pref. to Other/TIS-620 and it will be 8-bit and content-type:charset in mail header will show TIS-620. Mail subject is always UTF-8 encoded, some mail clients (esp. those webmails) cannot show mail subject properly if the mail subject is not all Latin.

So, I think Evolution can send/display Thai messages now, and the patch is _not_ required. If the patch break stuff inside, please just ignore it. Anyway, if it is harmless, please include TIS-620 in encoding preference so that Thai people can actually choose it just like other encodings/languages.

Thanks,
Kitt
