[...]2) ... so, to the major issue, which causes me some grief: Content Solution 2 doesn't seem to support national characters like, ñ, ø, å, æ, ü, etc. This error makes the software virtually useless for use with another language than English. Is there a workaround here?
I have to reply to my own post here, since I've managed to find a workaround:
The solution is to enter the unicode instead of the character itself in Content Solution. This actually work!
One example: Don't enter "México", enter "M & # 2 3 3 ; x i c o" (without the spaces) in Content Solution's editor. This will output "México" in the RSS feed. The same goes for the variables. Avoid unicode in the variable names -- there is no need for that.
To replace ordinary characters with unicode, you need a conversion table:
