I have an issue on one of the sites in my network. It seems that the charset in comments it not UTF, so letters like åäö are not displayed.
I have done alot of root cause analysis for this, including changing theme, disabling plugins, changing font and converting the database table FROM uft8 and then back, to make sure the database table wp_XX_comments is uft8.
None of this has worked, and the issue can not be reproduced on other blogs in the network. The only difference I can see with this blog is that it is on a mapped domain. I'm not sure how this would affect the charset at all, especially in comments perticularly, but it is the only thing I can see.
Any tips? Is domain mapping affecting this at all?
