Well, I tried something completely practical, rather than speculation, as EE ‘should’ do well with your request. The base character setting is utf8, which should handle most languages in the world.
- first I tried Chinese, the Simplified variant that is the language of continental China. This, with mixed English as an entry from a friend’s website, looked fine. I can read only a tiny bit of it, but am familiar with the characters, and these look to be all correct. The interspersed English was fine also.
- then I tried Korean, borrowing from newspapers there. Here the body text looked fine, and I do read a bit of it, as well as being quite familiar with the Korean writing. There was trouble, though, with the article titles. Something goes wrong there, and cuts off the end character or two. I suspect the ‘punctuation clearing’ etc. that’s done to clean up EE article titles. Such things brought to the attention of staff usually result in remarkably quick bug fixes - that’s one of the strengths and uniquenesses of the EE community.
- there’s a general issue also for titling, but that is very simple. EE makes up a ‘short title’ when you are editing the main article title, which is used as the url name for the article. This automatic creation of the short title doesn’t work with non-Roman scripts, but it’s right there in the form for you, and you can just type in a short non-accented name for the article. This ‘short title’ anyway wants to be roman and non-accented, to assure compatibility with web servers and browsers out there in a wide world.
In short, it looks pretty good, and I don’t think you’ll have trouble convincing the EE people to clean up whatever is sometimes interfering with the title, if you give them an example or two to work with. It might be that an option just needs to be added to defeat the cleaning-up, for such cases, if they can’t work out what is going on to alter higher-address characters. But I suspect they can actually fix the root difficulty rather easily.
On this aspect, though, you’ll need to hear from them. I think their intention is always to have a very clean as well as powerful ExpressionEngine.
Kind regards,
Clive
